CVSS
Base: 4.7
Impact:
Exploitability:
CWE CWE-200
CAPEC
  • Subverting Environment Variable Values
    The attacker directly or indirectly modifies environment variables used by or controlling the target software. The attacker's goal is to cause the target software to deviate from its expected operation in a manner that benefits the attacker.
  • Footprinting
    An attacker engages in probing and exploration activity to identify constituents and properties of the target. Footprinting is a general term to describe a variety of information gathering techniques, often used by attackers in preparation for some attack. It consists of using tools to learn as much as possible about the composition, configuration, and security mechanisms of the targeted application, system or network. Information that might be collected during a footprinting effort could include open ports, applications and their versions, network topology, and similar information. While footprinting is not intended to be damaging (although certain activities, such as network scans, can sometimes cause disruptions to vulnerable applications inadvertently) it may often pave the way for more damaging attacks.
  • Exploiting Trust in Client (aka Make the Client Invisible)
    An attack of this type exploits a programs' vulnerabilities in client/server communication channel authentication and data integrity. It leverages the implicit trust a server places in the client, or more importantly, that which the server believes is the client. An attacker executes this type of attack by placing themselves in the communication channel between client and server such that communication directly to the server is possible where the server believes it is communicating only with a valid client. There are numerous variations of this type of attack.
  • Browser Fingerprinting
    An attacker carefully crafts small snippets of Java Script to efficiently detect the type of browser the potential victim is using. Many web-based attacks need prior knowledge of the web browser including the version of browser to ensure successful exploitation of a vulnerability. Having this knowledge allows an attacker to target the victim with attacks that specifically exploit known or zero day weaknesses in the type and version of the browser used by the victim. Automating this process via Java Script as a part of the same delivery system used to exploit the browser is considered more efficient as the attacker can supply a browser fingerprinting method and integrate it with exploit code, all contained in Java Script and in response to the same web page request by the browser.
  • Session Credential Falsification through Prediction
    This attack targets predictable session ID in order to gain privileges. The attacker can predict the session ID used during a transaction to perform spoofing and session hijacking.
  • Reusing Session IDs (aka Session Replay)
    This attack targets the reuse of valid session ID to spoof the target system in order to gain privileges. The attacker tries to reuse a stolen session ID used previously during a transaction to perform spoofing and session hijacking. Another name for this type of attack is Session Replay.
  • Using Slashes in Alternate Encoding
    This attack targets the encoding of the Slash characters. An attacker would try to exploit common filtering problems related to the use of the slashes characters to gain access to resources on the target host. Directory-driven systems, such as file systems and databases, typically use the slash character to indicate traversal between directories or other container components. For murky historical reasons, PCs (and, as a result, Microsoft OSs) choose to use a backslash, whereas the UNIX world typically makes use of the forward slash. The schizophrenic result is that many MS-based systems are required to understand both forms of the slash. This gives the attacker many opportunities to discover and abuse a number of common filtering problems. The goal of this pattern is to discover server software that only applies filters to one version, but not the other.

    description It was discovered that memory present in the L1 data cache of an Intel CPU core may be exposed to a malicious process that is executing on the CPU core. This vulnerability is also known as L1 Terminal Fault (L1TF). A local attacker in a guest virtual machine could use this to expose sensitive information (memory from other guests or the host OS). (CVE-2018-3646) It was discovered that memory present in the L1 data cache of an Intel CPU core may be exposed to a malicious process that is executing on the CPU core. This vulnerability is also known as L1 Terminal Fault (L1TF). A local attacker could use this to expose sensitive information (memory from the kernel or other processes).

    description The openSUSE Leap 42.3 kernel was updated to 4.4.143 to receive various security and bugfixes. The following security bugs were fixed : - CVE-2017-18344: The timer_create syscall implementation in kernel/time/posix-timers.c didn't properly validate the sigevent->sigev_notify field, which leads to out-of-bounds access in the show_timer function (called when /proc/$PID/timers is read). This allowed userspace applications to read arbitrary kernel memory (on a kernel built with CONFIG_POSIX_TIMERS and CONFIG_CHECKPOINT_RESTORE) (bnc#1102851 bnc#1103580). - CVE-2018-10876: A flaw was found in Linux kernel in the ext4 filesystem code. A use-after-free is possible in ext4_ext_remove_space() function when mounting and operating a crafted ext4 image. (bnc#1099811) - CVE-2018-10877: Linux kernel ext4 filesystem is vulnerable to an out-of-bound access in the ext4_ext_drop_refs() function when operating on a crafted ext4 filesystem image. (bnc#1099846) - CVE-2018-10878: A flaw was found in the ext4 filesystem. A local user can cause an out-of-bounds write and a denial of service or unspecified other impact is possible by mounting and operating a crafted ext4 filesystem image. (bnc#1099813) - CVE-2018-10879: A flaw was found in the ext4 filesystem. A local user can cause a use-after-free in ext4_xattr_set_entry function and a denial of service or unspecified other impact may occur by renaming a file in a crafted ext4 filesystem image. (bnc#1099844) - CVE-2018-10880: Linux kernel is vulnerable to a stack-out-of-bounds write in the ext4 filesystem code when mounting and writing to a crafted ext4 image in ext4_update_inline_data(). An attacker could use this to cause a system crash and a denial of service. (bnc#1099845) - CVE-2018-10881: A flaw was found in the ext4 filesystem. A local user can cause an out-of-bound access in ext4_get_group_info function, a denial of service, and a system crash by mounting and operating on a crafted ext4 filesystem image. (bnc#1099864) - CVE-2018-10882: A flaw was found in the ext4 filesystem. A local user can cause an out-of-bound write in in fs/jbd2/transaction.c code, a denial of service, and a system crash by unmounting a crafted ext4 filesystem image. (bnc#1099849) - CVE-2018-10883: A flaw was found in the ext4 filesystem. A local user can cause an out-of-bounds write in jbd2_journal_dirty_metadata(), a denial of service, and a system crash by mounting and operating on a crafted ext4 filesystem image.

  • NASL family Windows : Microsoft Bulletins
    NASL id SMB_NT_MS18_AUG_4343897.NASL
    description The remote Windows host is missing security update 4343897. It is, therefore, affected by multiple vulnerabilities : - An information disclosure vulnerability exists when the Windows kernel improperly handles objects in memory. An attacker who successfully exploited this vulnerability could obtain information to further compromise the users system. (CVE-2018-8341, CVE-2018-8348) - A remote code execution vulnerability exists when the Windows font library improperly handles specially crafted embedded fonts. An attacker who successfully exploited the vulnerability could take control of the affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. (CVE-2018-8344) - An elevation of privilege vulnerability exists in the Network Driver Interface Specification (NDIS) when ndis.sys fails to check the length of a buffer prior to copying memory to it. (CVE-2018-8343) - A remote code execution vulnerability exists in "Microsoft COM for Windows" when it fails to properly handle serialized objects. An attacker who successfully exploited the vulnerability could use a specially crafted file or script to perform actions. In an email attack scenario, an attacker could exploit the vulnerability by sending the specially crafted file to the user and convincing the user to open the file. (CVE-2018-8349) - An elevation of privilege vulnerability exists when the DirectX Graphics Kernel (DXGKRNL) driver improperly handles objects in memory. An attacker who successfully exploited this vulnerability could run processes in an elevated context. (CVE-2018-8400, CVE-2018-8401, CVE-2018-8405, CVE-2018-8406) - A remote code execution vulnerability exists in the way that the ChakraCore scripting engine handles objects in memory. The vulnerability could corrupt memory in such a way that an attacker could execute arbitrary code in the context of the current user. An attacker who successfully exploited the vulnerability could gain the same user rights as the current user. (CVE-2018-8390) - A remote code execution vulnerability exists when the Windows Shell does not properly validate file paths. An attacker who successfully exploited this vulnerability could run arbitrary code in the context of the current user. If the current user is logged on as an administrator, an attacker could take control of the affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with elevated privileges. Users whose accounts are configured to have fewer privileges on the system could be less impacted than users who operate with administrative privileges. (CVE-2018-8414) - A security feature bypass vulnerability exists in Device Guard that could allow an attacker to inject malicious code into a Windows PowerShell session. An attacker who successfully exploited this vulnerability could inject code into a trusted PowerShell process to bypass the Device Guard Code Integrity policy on the local machine. (CVE-2018-8200, CVE-2018-8204) - A remote code execution vulnerability exists in the way the scripting engine handles objects in memory in Microsoft browsers. The vulnerability could corrupt memory in such a way that an attacker could execute arbitrary code in the context of the current user. An attacker who successfully exploited the vulnerability could gain the same user rights as the current user. (CVE-2018-8355, CVE-2018-8372, CVE-2018-8385) - An elevation of privilege vulnerability exists in Microsoft Windows when the Windows kernel fails to properly handle parsing of certain symbolic links. An attacker who successfully exploited this vulnerability could potentially access privileged registry keys and thereby elevate permissions. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. (CVE-2018-8347) - A remote code execution vulnerability exists when Microsoft Windows PDF Library improperly handles objects in memory. The vulnerability could corrupt memory in a way that enables an attacker to execute arbitrary code in the context of the current user. An attacker who successfully exploited the vulnerability could gain the same user rights as the current user. If the current user is logged on with administrative user rights, an attacker could take control of an affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. (CVE-2018-8350) - A remote code execution vulnerability exists in Microsoft Windows that could allow remote code execution if a .LNK file is processed. An attacker who successfully exploited this vulnerability could gain the same user rights as the local user. (CVE-2018-8345) - A information disclosure vulnerability exists when WebAudio Library improperly handles audio requests. An attacker who has successfully exploited this vulnerability might be able to read privileged data across trust boundaries. In browsing scenarios, an attacker could convince a user to visit a malicious site and leverage the vulnerability to obtain privileged information from the browser process, such as sensitive data from other opened tabs. An attacker could also inject malicious code into advertising networks used by trusted sites or embed malicious code on a compromised, but trusted, site. The update addresses the vulnerability by correcting how the WebAudio Library handles audio requests. (CVE-2018-8370) - An elevation of privilege vulnerability exists in the Windows Installer when the Windows Installer fails to properly sanitize input leading to an insecure library loading behavior. A locally authenticated attacker could run arbitrary code with elevated system privileges. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. The security update addresses the vulnerability by correcting the input sanitization error to preclude unintended elevation. (CVE-2018-8339) - A remote code execution vulnerability exists in the way that the Chakra scripting engine handles objects in memory in Microsoft Edge. The vulnerability could corrupt memory in such a way that an attacker could execute arbitrary code in the context of the current user. An attacker who successfully exploited the vulnerability could gain the same user rights as the current user. (CVE-2018-8266, CVE-2018-8381) - A remote code execution vulnerability exists when Internet Explorer improperly validates hyperlinks before loading executable libraries. An attacker who successfully exploited this vulnerability could take control of an affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. (CVE-2018-8316) - An elevation of privilege vulnerability exists in Windows when the Win32k component fails to properly handle objects in memory. An attacker who successfully exploited this vulnerability could run arbitrary code in kernel mode. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. (CVE-2018-8399, CVE-2018-8404) - An information disclosure vulnerability exists when the Windows GDI component improperly discloses the contents of its memory. An attacker who successfully exploited the vulnerability could obtain information to further compromise the users system. There are multiple ways an attacker could exploit the vulnerability, such as by convincing a user to open a specially crafted document, or by convincing a user to visit an untrusted webpage. The security update addresses the vulnerability by correcting how the Windows GDI component handles objects in memory. (CVE-2018-8394, CVE-2018-8398) - A remote code execution vulnerability exists in the way that Microsoft browsers access objects in memory. The vulnerability could corrupt memory in a way that could allow an attacker to execute arbitrary code in the context of the current user. An attacker who successfully exploited the vulnerability could gain the same user rights as the current user. (CVE-2018-8403) - An information disclosure vulnerability exists when affected Microsoft browsers improperly allow cross-frame interaction. An attacker who successfully exploited this vulnerability could allow an attacker to obtain browser frame or window state from a different domain. For an attack to be successful, an attacker must persuade a user to open a malicious website from a secure website. This update addresses the vulnerability by denying permission to read the state of the object model, to which frames or windows on different domains should not have access. (CVE-2018-8351) - An elevation of privilege vulnerability exists in Microsoft browsers allowing sandbox escape. An attacker who successfully exploited the vulnerability could use the sandbox escape to elevate privileges on an affected system. This vulnerability by itself does not allow arbitrary code execution; however, it could allow arbitrary code to be run if the attacker uses it in combination with another vulnerability (such as a remote code execution vulnerability or another elevation of privilege vulnerability) that is capable of leveraging the elevated privileges when code execution is attempted. (CVE-2018-8357) - An Elevation of Privilege vulnerability exists when Diagnostics Hub Standard Collector allows file creation in arbitrary locations. (CVE-2018-0952) - A remote code execution vulnerability exists in the way that the scripting engine handles objects in memory in Internet Explorer. The vulnerability could corrupt memory in such a way that an attacker could execute arbitrary code in the context of the current user. An attacker who successfully exploited the vulnerability could gain the same user rights as the current user. (CVE-2018-8353, CVE-2018-8371, CVE-2018-8373, CVE-2018-8389) - A remote code execution vulnerability exists when Microsoft Edge improperly accesses objects in memory. The vulnerability could corrupt memory in such a way that enables an attacker to execute arbitrary code in the context of the current user. An attacker who successfully exploited the vulnerability could gain the same user rights as the current user. (CVE-2018-8377) - An information disclosure vulnerability exists in Microsoft .NET Framework that could allow an attacker to access information in multi-tenant environments. The vulnerability is caused when .NET Framework is used in high-load/high-density network connections where content from one stream can blend into another stream. (CVE-2018-8360) - A spoofing vulnerability exists when Microsoft Edge improperly handles specific HTML content. An attacker who successfully exploited this vulnerability could trick a user into believing that the user was on a legitimate website. The specially crafted website could either spoof content or serve as a pivot to chain an attack with other vulnerabilities in web services. (CVE-2018-8388)

    title KB4343897: Windows 10 Version 1709 And Windows Server Version 1709 August 2018 Security Update (Foreshadow)
  • NASL family Red Hat Local Security Checks
    NASL id REDHAT-RHSA-2018-2390.NASL
    description An update for kernel is now available for Red Hat Enterprise Linux 6. Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section. [Updated 16th August 2018] The original errata text was missing reference to CVE-2018-5390 fix. We have updated the errata text to correct this issue. No changes have been made to the packages. The kernel packages contain the Linux kernel, the core of any Linux operating system. Security Fix(es) : * Modern operating systems implement virtualization of physical memory to efficiently use available system resources and provide inter-domain protection through access control and isolation. The L1TF issue was found in the way the x86 microprocessor designs have implemented speculative execution of instructions (a commonly used performance optimisation) in combination with handling of page-faults caused by terminated virtual to physical address resolving process. As a result, an unprivileged attacker could use this flaw to read privileged memory of the kernel or other processes and/or cross guest/host boundaries to read host memory by conducting targeted cache side-channel attacks. (CVE-2018-3620, CVE-2018-3646) * An industry-wide issue was found in the way many modern microprocessor designs have implemented speculative execution of instructions past bounds check. The flaw relies on the presence of a precisely-defined instruction sequence in the privileged code and the fact that memory writes occur to an address which depends on the untrusted value. Such writes cause an update into the microprocessor's data cache even for speculatively executed instructions that never actually commit (retire). As a result, an unprivileged attacker could use this flaw to influence speculative execution and/or read privileged memory by conducting targeted cache side-channel attacks. (CVE-2018-3693) * A flaw named SegmentSmack was found in the way the Linux kernel handled specially crafted TCP packets. A remote attacker could use this flaw to trigger time and calculation expensive calls to tcp_collapse_ofo_queue() and tcp_prune_ofo_queue() functions by sending specially modified packets within ongoing TCP sessions which could lead to a CPU saturation and hence a denial of service on the system. Maintaining the denial of service condition requires continuous two-way TCP sessions to a reachable open port, thus the attacks cannot be performed using spoofed IP addresses. (CVE-2018-5390) * kernel: kvm: vmx: host GDT limit corruption (CVE-2018-10901) * kernel: Use-after-free in snd_pcm_info function in ALSA subsystem potentially leads to privilege escalation (CVE-2017-0861) * kernel: Use-after-free in snd_seq_ioctl_create_port() (CVE-2017-15265) * kernel: race condition in snd_seq_write() may lead to UAF or OOB-access (CVE-2018-7566) * kernel: Race condition in sound system can lead to denial of service (CVE-2018-1000004) For more details about the security issue(s), including the impact, a CVSS score, and other related information, refer to the CVE page(s) listed in the References section. Red Hat would like to thank Intel OSSIRT (Intel.com) for reporting CVE-2018-3620 and CVE-2018-3646; Vladimir Kiriansky (MIT) and Carl Waldspurger (Carl Waldspurger Consulting) for reporting CVE-2018-3693; Juha-Matti Tilli (Aalto University, Department of Communications and Networking and Nokia Bell Labs) for reporting CVE-2018-5390; and Vegard Nossum (Oracle Corporation) for reporting CVE-2018-10901. Bug Fix(es) : * The Least recently used (LRU) operations are batched by caching pages in per-cpu page vectors to prevent contention of the heavily used lru_lock spinlock. The page vectors can hold even the compound pages. Previously, the page vectors were cleared only if they were full. Subsequently, the amount of memory held in page vectors, which is not reclaimable, was sometimes too high. Consequently the page reclamation started the Out of Memory (OOM) killing processes. With this update, the underlying source code has been fixed to clear LRU page vectors each time when a compound page is added to them. As a result, OOM killing processes due to high amounts of memory held in page vectors no longer occur. (BZ#1575819)

    NASL id REDHAT-RHSA-2018-2393.NASL
    description An update for kernel is now available for Red Hat Enterprise Linux 6.5 Advanced Update Support. Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section. The kernel packages contain the Linux kernel, the core of any Linux operating system. Security Fix(es) : * Modern operating systems implement virtualization of physical memory to efficiently use available system resources and provide inter-domain protection through access control and isolation. The L1TF issue was found in the way the x86 microprocessor designs have implemented speculative execution of instructions (a commonly used performance optimisation) in combination with handling of page-faults caused by terminated virtual to physical address resolving process. As a result, an unprivileged attacker could use this flaw to read privileged memory of the kernel or other processes and/or cross guest/host boundaries to read host memory by conducting targeted cache side-channel attacks. (CVE-2018-3620, CVE-2018-3646) * kernel: kvm: vmx: host GDT limit corruption (CVE-2018-10901) For more details about the security issue(s), including the impact, a CVSS score, and other related information, refer to the CVE page(s) listed in the References section.

  • NASL family Windows : Microsoft Bulletins
    NASL id SMB_NT_MS18_AUG_4343898.NASL
    description The remote Windows host is missing security update 4343888 or cumulative update 4343898. It is, therefore, affected by multiple vulnerabilities : - A remote code execution vulnerability exists in the way that Microsoft browsers access objects in memory. The vulnerability could corrupt memory in a way that could allow an attacker to execute arbitrary code in the context of the current user. An attacker who successfully exploited the vulnerability could gain the same user rights as the current user. (CVE-2018-8403) - An information disclosure vulnerability exists in Microsoft .NET Framework that could allow an attacker to access information in multi-tenant environments. The vulnerability is caused when .NET Framework is used in high-load/high-density network connections where content from one stream can blend into another stream. (CVE-2018-8360) - An information disclosure vulnerability exists when the Windows kernel improperly handles objects in memory. An attacker who successfully exploited this vulnerability could obtain information to further compromise the users system. (CVE-2018-8341, CVE-2018-8348) - A remote code execution vulnerability exists when the Windows font library improperly handles specially crafted embedded fonts. An attacker who successfully exploited the vulnerability could take control of the affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. (CVE-2018-8344) - An elevation of privilege vulnerability exists in Windows when the Win32k component fails to properly handle objects in memory. An attacker who successfully exploited this vulnerability could run arbitrary code in kernel mode. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. (CVE-2018-8404) - A remote code execution vulnerability exists when Internet Explorer improperly validates hyperlinks before loading executable libraries. An attacker who successfully exploited this vulnerability could take control of an affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. (CVE-2018-8316) - A remote code execution vulnerability exists in the way the scripting engine handles objects in memory in Microsoft browsers. The vulnerability could corrupt memory in such a way that an attacker could execute arbitrary code in the context of the current user. An attacker who successfully exploited the vulnerability could gain the same user rights as the current user. (CVE-2018-8355, CVE-2018-8372, CVE-2018-8385) - A remote code execution vulnerability exists in the way that the scripting engine handles objects in memory in Internet Explorer. The vulnerability could corrupt memory in such a way that an attacker could execute arbitrary code in the context of the current user. An attacker who successfully exploited the vulnerability could gain the same user rights as the current user. (CVE-2018-8353, CVE-2018-8371, CVE-2018-8373, CVE-2018-8389) - A remote code execution vulnerability exists in Microsoft Windows that could allow remote code execution if a .LNK file is processed. An attacker who successfully exploited this vulnerability could gain the same user rights as the local user. (CVE-2018-8345) - An elevation of privilege vulnerability exists when the DirectX Graphics Kernel (DXGKRNL) driver improperly handles objects in memory. An attacker who successfully exploited this vulnerability could run processes in an elevated context. (CVE-2018-8405) - An elevation of privilege vulnerability exists in the Network Driver Interface Specification (NDIS) when ndis.sys fails to check the length of a buffer prior to copying memory to it. (CVE-2018-8343) - An information disclosure vulnerability exists when the Windows GDI component improperly discloses the contents of its memory. An attacker who successfully exploited the vulnerability could obtain information to further compromise the users system. There are multiple ways an attacker could exploit the vulnerability, such as by convincing a user to open a specially crafted document, or by convincing a user to visit an untrusted webpage. The security update addresses the vulnerability by correcting how the Windows GDI component handles objects in memory. (CVE-2018-8394, CVE-2018-8398) - A remote code execution vulnerability exists in "Microsoft COM for Windows" when it fails to properly handle serialized objects. An attacker who successfully exploited the vulnerability could use a specially crafted file or script to perform actions. In an email attack scenario, an attacker could exploit the vulnerability by sending the specially crafted file to the user and convincing the user to open the file. (CVE-2018-8349) - An elevation of privilege vulnerability exists in the Windows Installer when the Windows Installer fails to properly sanitize input leading to an insecure library loading behavior. A locally authenticated attacker could run arbitrary code with elevated system privileges. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. The security update addresses the vulnerability by correcting the input sanitization error to preclude unintended elevation. (CVE-2018-8339) - A security feature bypass vulnerability exists when Active Directory Federation Services (AD FS) improperly handles multi-factor authentication requests. (CVE-2018-8340) - An information disclosure vulnerability exists when affected Microsoft browsers improperly allow cross-frame interaction. An attacker who successfully exploited this vulnerability could allow an attacker to obtain browser frame or window state from a different domain. For an attack to be successful, an attacker must persuade a user to open a malicious website from a secure website. This update addresses the vulnerability by denying permission to read the state of the object model, to which frames or windows on different domains should not have access. (CVE-2018-8351)

    description On certain Intel 64-bit x86 systems there is a period of time during terminal fault handling where the CPU may use speculative execution to try to load data. The CPU may speculatively access the level 1 data cache (L1D). Data which would otherwise be protected may then be determined by using side channel methods. This issue affects bhyve on FreeBSD/amd64 systems. Impact : An attacker executing user code, or kernel code inside of a virtual machine, may be able to read secret data from the kernel or from another virtual machine.

    description According to the versions of the kernel packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities : - Modern operating systems implement virtualization of physical memory to efficiently use available system resources and provide inter-domain protection through access control and isolation. The L1TF issue was found in the way the x86 microprocessor designs have implemented speculative execution of instructions (a commonly used performance optimisation) in combination with handling of page-faults caused by terminated virtual to physical address resolving process. As a result, an unprivileged attacker could use this flaw to read privileged memory of the kernel or other processes and/or cross guest/host boundaries to read host memory by conducting targeted cache side-channel attacks. (CVE-2018-3620, CVE-2018-3646) - A flaw named SegmentSmack was found in the way the Linux kernel handled specially crafted TCP packets. A remote attacker could use this flaw to trigger time and calculation expensive calls to tcp_collapse_ofo_queue() and tcp_prune_ofo_queue() functions by sending specially modified packets within ongoing TCP sessions which could lead to a CPU saturation and hence a denial of service on the system. Maintaining the denial of service condition requires continuous two-way TCP sessions to a reachable open port, thus the attacks cannot be performed using spoofed IP addresses. (CVE-2018-5390) - A flaw named FragmentSmack was found in the way the Linux kernel handled reassembly of fragmented IPv4 and IPv6 packets. A remote attacker could use this flaw to trigger time and calculation expensive fragment reassembly algorithm by sending specially crafted packets which could lead to a CPU saturation and hence a denial of service on the system.(CVE-2018-5391) Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

    description Security researchers identified speculative execution side-channel methods which have the potential to improperly gather sensitive data from multiple types of computing devices with different vendors’ processors and operating systems. This update requires an update to the intel-microcode package, which is non-free. It is related to DLA-1446-1 and adds more mitigations for additional types of Intel processors. For more information please also read the official Intel security advisories at : https://www.intel.com/content/www/us/en/security-center/advisory/intel -s a-00088.html https://www.intel.com/content/www/us/en/security-center/advisory/intel -s a-00115.html https://www.intel.com/content/www/us/en/security-center/advisory/intel -s a-00161.html For Debian 8 'Jessie', these problems have been fixed in version 3.20180807a.1~deb8u1. We recommend that you upgrade your intel-microcode packages. NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

  • NASL family Virtuozzo Local Security Checks
    NASL id VIRTUOZZO_VZA-2018-063.NASL
    description According to the versions of the OVMF / crit / criu / criu-devel / ksm-vz / etc packages installed, the Virtuozzo installation on the remote host is affected by the following vulnerabilities : - A flaw was found in the Linux kernel's skcipher component, which affects the skcipher_recvmsg function. Attackers using a specific input can lead to a privilege escalation. - Modern operating systems implement virtualization of physical memory to efficiently use available system resources and provide inter-domain protection through access control and isolation. The L1TF issue was found in the way the x86 microprocessor designs have implemented speculative execution of instructions (a commonly used performance optimisation) in combination with handling of page-faults caused by terminated virtual to physical address resolving process. As a result, an unprivileged attacker could use this flaw to read privileged memory of the kernel or other processes and/or cross guest/host boundaries to read host memory by conducting targeted cache side-channel attacks. - An industry-wide issue was found in the way many modern microprocessor designs have implemented speculative execution of instructions past bounds check. The flaw relies on the presence of a precisely-defined instruction sequence in the privileged code and the fact that memory writes occur to an address which depends on the untrusted value. Such writes cause an update into the microprocessor's data cache even for speculatively executed instructions that never actually commit (retire). As a result, an unprivileged attacker could use this flaw to influence speculative execution and/or read privileged memory by conducting targeted cache side-channel attacks. - A flaw named SegmentSmack was found in the way the Linux kernel handled specially crafted TCP packets. A remote attacker could use this flaw to trigger time and calculation expensive calls to tcp_collapse_ofo_queue() and tcp_prune_ofo_queue() functions by sending specially modified packets within ongoing TCP sessions which could lead to a CPU saturation and hence a denial of service on the system. Maintaining the denial of service condition requires continuous two-way TCP sessions to a reachable open port, thus the attacks cannot be performed using spoofed IP addresses. - ALSA sequencer core initializes the event pool on demand by invoking snd_seq_pool_init() when the first write happens and the pool is empty. A user can reset the pool size manually via ioctl concurrently, and this may lead to UAF or out-of-bound access. - The do_get_mempolicy() function in mm/mempolicy.c in the Linux kernel allows local users to hit a use-after-free bug via crafted system calls and thus cause a denial of service (DoS) or possibly have unspecified other impact. Due to the nature of the flaw, privilege escalation cannot be fully ruled out. Note that Tenable Network Security has extracted the preceding description block directly from the Virtuozzo security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

    NASL id SUSE_SU-2018-2328-1.NASL
    description The SUSE Linux Enterprise 12 SP3 kernel was updated to 4.4.143 to receive various security and bugfixes. The following security bugs were fixed : - CVE-2018-5390 aka 'SegmentSmack': Linux kernel could be forced to make very expensive calls to tcp_collapse_ofo_queue() and tcp_prune_ofo_queue() for every incoming packet which can lead to a denial of service (bnc#1102340). - CVE-2018-14734: drivers/infiniband/core/ucma.c in the Linux kernel allowed ucma_leave_multicast to access a certain data structure after a cleanup step in ucma_process_join, which allowed attackers to cause a denial of service (use-after-free) (bnc#1103119). - CVE-2017-18344: The timer_create syscall implementation in kernel/time/posix-timers.c didn't properly validate the sigevent->sigev_notify field, which lead to out-of-bounds access in the show_timer function (called when /proc/$PID/timers is read). This allowed userspace applications to read arbitrary kernel memory (on a kernel built with CONFIG_POSIX_TIMERS and CONFIG_CHECKPOINT_RESTORE) (bnc#1102851 bnc#1103580). - CVE-2018-3620: Local attackers on baremetal systems could use speculative code patterns on hyperthreaded processors to read data present in the L1 Datacache used by other hyperthreads on the same CPU core, potentially leaking sensitive data. (bnc#1087081). - CVE-2018-3646: Local attackers in virtualized guest systems could use speculative code patterns on hyperthreaded processors to read data present in the L1 Datacache used by other hyperthreads on the same CPU core, potentially leaking sensitive data, even from other virtual machines or the host system. (bnc#1089343). The update package also includes non-security fixes. See advisory for details.

    description The SUSE Linux Enterprise 12 SP1 LTSS kernel was updated to receive various security and bugfixes. The following security bugs were fixed : - CVE-2018-3620: Local attackers on baremetal systems could use speculative code patterns on hyperthreaded processors to read data present in the L1 Datacache used by other hyperthreads on the same CPU core, potentially leaking sensitive data. (bnc#1087081). - CVE-2018-3646: Local attackers in virtualized guest systems could use speculative code patterns on hyperthreaded processors to read data present in the L1 Datacache used by other hyperthreads on the same CPU core, potentially leaking sensitive data, even from other virtual machines or the host system. (bnc#1089343). - CVE-2018-14734: drivers/infiniband/core/ucma.c allowed ucma_leave_multicast to access a certain data structure after a cleanup step in ucma_process_join, which allowed attackers to cause a denial of service (use-after-free) (bnc#1103119). - CVE-2018-13053: The alarm_timer_nsleep function in kernel/time/alarmtimer.c had via a large relative timeout because ktime_add_safe is not used (bnc#1099924). - CVE-2018-13405: The inode_init_owner function in fs/inode.c allowed local users to create files with an unintended group ownership, in a scenario where a directory is SGID to a certain group and is writable by a user who is not a member of that group. Here, the non-member can trigger creation of a plain file whose group ownership is that group. The intended behavior was that the non-member can trigger creation of a directory (but not a plain file) whose group ownership is that group. The non-member can escalate privileges by making the plain file executable and SGID (bnc#1100416). - CVE-2018-13406: An integer overflow in the uvesafb_setcmap function in drivers/video/fbdev/uvesafb.c could result in local attackers being able to crash the kernel or potentially elevate privileges because kmalloc_array is not used (bnc#1098016 bnc#1100418).

  • NASL family Virtuozzo Local Security Checks
    NASL id VIRTUOZZO_VZA-2018-055.NASL
    description According to the versions of the cpupools / cpupools-features / etc packages installed, the Virtuozzo installation on the remote host is affected by the following vulnerabilities : - Modern operating systems implement virtualization of physical memory to efficiently use available system resources and provide inter-domain protection through access control and isolation. The L1TF issue was found in the way the x86 microprocessor designs have implemented speculative execution of instructions (a commonly used performance optimisation) in combination with handling of page-faults caused by terminated virtual to physical address resolving process. As a result, an unprivileged attacker could use this flaw to read privileged memory of the kernel or other processes and/or cross guest/host boundaries to read host memory by conducting targeted cache side-channel attacks. - An industry-wide issue was found in the way many modern microprocessor designs have implemented speculative execution of instructions past bounds check. The flaw relies on the presence of a precisely-defined instruction sequence in the privileged code and the fact that memory writes occur to an address which depends on the untrusted value. Such writes cause an update into the microprocessor's data cache even for speculatively executed instructions that never actually commit (retire). As a result, an unprivileged attacker could use this flaw to influence speculative execution and/or read privileged memory by conducting targeted cache side-channel attacks. - A flaw named SegmentSmack was found in the way the Linux kernel handled specially crafted TCP packets. A remote attacker could use this flaw to trigger time and calculation expensive calls to tcp_collapse_ofo_queue() and tcp_prune_ofo_queue() functions by sending specially modified packets within ongoing TCP sessions which could lead to a CPU saturation and hence a denial of service on the system. Maintaining the denial of service condition requires continuous two-way TCP sessions to a reachable open port, thus the attacks cannot be performed using spoofed IP addresses. - A flaw was found in Linux kernel's KVM virtualization subsystem. The VMX code does not restore the GDT.LIMIT to the previous host value, but instead sets it to 64KB. With a corrupted GDT limit a host's userspace code has an ability to place malicious entries in the GDT, particularly to the per-cpu variables. An attacker can use this to escalate their privileges. - Use-after-free vulnerability in the snd_pcm_info() function in the ALSA subsystem in the Linux kernel allows attackers to induce a kernel memory corruption and possibly crash or lock up a system. Due to the nature of the flaw, a privilege escalation cannot be fully ruled out, although we believe it is unlikely. - ALSA sequencer core initializes the event pool on demand by invoking snd_seq_pool_init() when the first write happens and the pool is empty. A user can reset the pool size manually via ioctl concurrently, and this may lead to UAF or out-of-bound access. - In the Linux kernel versions 4.12, 3.10, 2.6, and possibly earlier, a race condition vulnerability exists in the sound system allowing for a potential deadlock and memory corruption due to use-after-free condition and thus denial of service. Due to the nature of the flaw, privilege escalation cannot be fully ruled out, although we believe it is unlikely. Note that Tenable Network Security has extracted the preceding description block directly from the Virtuozzo security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

    description From Red Hat Security Advisory 2018:2390 : An update for kernel is now available for Red Hat Enterprise Linux 6. Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section. [Updated 16th August 2018] The original errata text was missing reference to CVE-2018-5390 fix. We have updated the errata text to correct this issue. No changes have been made to the packages. The kernel packages contain the Linux kernel, the core of any Linux operating system. Security Fix(es) : * Modern operating systems implement virtualization of physical memory to efficiently use available system resources and provide inter-domain protection through access control and isolation. The L1TF issue was found in the way the x86 microprocessor designs have implemented speculative execution of instructions (a commonly used performance optimisation) in combination with handling of page-faults caused by terminated virtual to physical address resolving process. As a result, an unprivileged attacker could use this flaw to read privileged memory of the kernel or other processes and/or cross guest/host boundaries to read host memory by conducting targeted cache side-channel attacks. (CVE-2018-3620, CVE-2018-3646) * An industry-wide issue was found in the way many modern microprocessor designs have implemented speculative execution of instructions past bounds check. The flaw relies on the presence of a precisely-defined instruction sequence in the privileged code and the fact that memory writes occur to an address which depends on the untrusted value. Such writes cause an update into the microprocessor's data cache even for speculatively executed instructions that never actually commit (retire). As a result, an unprivileged attacker could use this flaw to influence speculative execution and/or read privileged memory by conducting targeted cache side-channel attacks. (CVE-2018-3693) * A flaw named SegmentSmack was found in the way the Linux kernel handled specially crafted TCP packets. A remote attacker could use this flaw to trigger time and calculation expensive calls to tcp_collapse_ofo_queue() and tcp_prune_ofo_queue() functions by sending specially modified packets within ongoing TCP sessions which could lead to a CPU saturation and hence a denial of service on the system. Maintaining the denial of service condition requires continuous two-way TCP sessions to a reachable open port, thus the attacks cannot be performed using spoofed IP addresses. (CVE-2018-5390) * kernel: kvm: vmx: host GDT limit corruption (CVE-2018-10901) * kernel: Use-after-free in snd_pcm_info function in ALSA subsystem potentially leads to privilege escalation (CVE-2017-0861) * kernel: Use-after-free in snd_seq_ioctl_create_port() (CVE-2017-15265) * kernel: race condition in snd_seq_write() may lead to UAF or OOB-access (CVE-2018-7566) * kernel: Race condition in sound system can lead to denial of service (CVE-2018-1000004) For more details about the security issue(s), including the impact, a CVSS score, and other related information, refer to the CVE page(s) listed in the References section. Red Hat would like to thank Intel OSSIRT (Intel.com) for reporting CVE-2018-3620 and CVE-2018-3646; Vladimir Kiriansky (MIT) and Carl Waldspurger (Carl Waldspurger Consulting) for reporting CVE-2018-3693; Juha-Matti Tilli (Aalto University, Department of Communications and Networking and Nokia Bell Labs) for reporting CVE-2018-5390; and Vegard Nossum (Oracle Corporation) for reporting CVE-2018-10901. Bug Fix(es) : * The Least recently used (LRU) operations are batched by caching pages in per-cpu page vectors to prevent contention of the heavily used lru_lock spinlock. The page vectors can hold even the compound pages. Previously, the page vectors were cleared only if they were full. Subsequently, the amount of memory held in page vectors, which is not reclaimable, was sometimes too high. Consequently the page reclamation started the Out of Memory (OOM) killing processes. With this update, the underlying source code has been fixed to clear LRU page vectors each time when a compound page is added to them. As a result, OOM killing processes due to high amounts of memory held in page vectors no longer occur. (BZ#1575819)

    NASL id SUSE_SU-2018-2332-1.NASL
    description The SUSE Linux Enterprise 11 SP4 kernel was updated to receive various security and bugfixes. The following security bugs were fixed : - CVE-2018-3620: Local attackers on baremetal systems could use speculative code patterns on hyperthreaded processors to read data present in the L1 Datacache used by other hyperthreads on the same CPU core, potentially leaking sensitive data. (bnc#1087081). - CVE-2018-3646: Local attackers in virtualized guest systems could use speculative code patterns on hyperthreaded processors to read data present in the L1 Datacache used by other hyperthreads on the same CPU core, potentially leaking sensitive data, even from other virtual machines or the host system. (bnc#1089343). - CVE-2018-1000204: A malformed SG_IO ioctl issued for a SCSI device could lead to a local kernel information leak manifesting in up to approximately 1000 memory pages copied to the userspace. The problem has limited scope as non-privileged users usually have no permissions to access SCSI device files. (bnc#1096728). - CVE-2018-13053: The alarm_timer_nsleep function in kernel/time/alarmtimer.c had an integer overflow via a large relative timeout because ktime_add_safe is not used (bnc#1099924). - CVE-2018-13406: An integer overflow in the uvesafb_setcmap function in drivers/video/fbdev/uvesafb.c could result in local attackers being able to crash the kernel or potentially elevate privileges because kmalloc_array is not used (bnc#1098016 bnc#1100418). - CVE-2016-8405: An information disclosure vulnerability in kernel components including the ION subsystem, Binder, USB driver and networking subsystem could enable a local malicious application to access data outside of its permission levels. (bnc#1099942). - CVE-2018-5814: Multiple race condition errors when handling probe, disconnect, and rebind operations could be exploited to trigger a use-after-free condition or a NULL pointer dereference by sending multiple USB over IP packets (bnc#1096480). - CVE-2018-12233: In the ea_get function in fs/jfs/xattr.c a memory corruption bug in JFS can be triggered by calling setxattr twice with two different extended attribute names on the same file. This vulnerability can be triggered by an unprivileged user with the ability to create files and execute programs. (bnc#1097234). - CVE-2017-13305: A information disclosure vulnerability in the Upstream kernel encrypted-keys. (bnc#1094353). - CVE-2018-1130: A NULL pointer dereference in dccp_write_xmit() function in net/dccp/output.c allowed a local user to cause a denial of service by a number of certain crafted system calls (bnc#1092904). - CVE-2018-1068: A flaw was found in the implementation of 32-bit syscall interface for bridging. This allowed a privileged user to arbitrarily write to a limited range of kernel memory (bnc#1085107). - CVE-2018-5803: An error in the '_sctp_make_chunk()' function (net/sctp/sm_make_chunk.c) when handling SCTP packets length could be exploited to cause a kernel crash (bnc#1083900). - CVE-2018-7492: A NULL pointer dereference was found in the net/rds/rdma.c __rds_rdma_map() function allowed local attackers to cause a system panic and a denial-of-service, related to RDS_GET_MR and RDS_GET_MR_FOR_DEST (bnc#1082962). The update package also includes non-security fixes. See advisory for details. Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory.

  • NASL family Red Hat Local Security Checks
    NASL id REDHAT-RHSA-2018-2387.NASL
    description An update for kernel is now available for Red Hat Enterprise Linux 7.4 Extended Update Support. Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section. The kernel packages contain the Linux kernel, the core of any Linux operating system. Security Fix(es) : * Modern operating systems implement virtualization of physical memory to efficiently use available system resources and provide inter-domain protection through access control and isolation. The L1TF issue was found in the way the x86 microprocessor designs have implemented speculative execution of instructions (a commonly used performance optimisation) in combination with handling of page-faults caused by terminated virtual to physical address resolving process. As a result, an unprivileged attacker could use this flaw to read privileged memory of the kernel or other processes and/or cross guest/host boundaries to read host memory by conducting targeted cache side-channel attacks. (CVE-2018-3620, CVE-2018-3646) * An industry-wide issue was found in the way many modern microprocessor designs have implemented speculative execution of Load & Store instructions (a commonly used performance optimization). It relies on the presence of a precisely-defined instruction sequence in the privileged code as well as the fact that memory read from address to which a recent memory write has occurred may see an older value and subsequently cause an update into the microprocessor's data cache even for speculatively executed instructions that never actually commit (retire). As a result, an unprivileged attacker could use this flaw to read privileged memory by conducting targeted cache side-channel attacks. (CVE-2018-3639) Red Hat would like to thank Intel OSSIRT (Intel.com) for reporting CVE-2018-3620 and CVE-2018-3646 and Ken Johnson (Microsoft Security Response Center) and Jann Horn (Google Project Zero) for reporting CVE-2018-3639. Bug Fix(es) : * Previously, configurations with the little-endian variant of IBM Power Systems CPU architectures and Hard Disk Drives (HDD) designed according to Nonvolatile Memory Express (NVMe) open standards, experienced crashes during shutdown or reboot due to race conditions of CPUs. As a consequence, the sysfs pseudo file system threw a stack trace report about an attempt to create a duplicate entry in sysfs. This update modifies the source code so that the irq_dispose_mapping() function is called first and the msi_bitmap_free_hwirqs() function is called afterwards. As a result, the race condition no longer appears in the described scenario. (BZ#1570510) * When switching from the indirect branch speculation (IBRS) feature to the retpolines feature, the IBRS state of some CPUs was sometimes not handled correctly. Consequently, some CPUs were left with the IBRS Model-Specific Register (MSR) bit set to 1, which could lead to performance issues. With this update, the underlying source code has been fixed to clear the IBRS MSR bits correctly, thus fixing the bug. (BZ#1586147) * During a balloon reset, page pointers were not correctly initialized after unmapping the memory. Consequently, on the VMware ESXi hypervisor with 'Fault Tolerance' and 'ballooning' enabled, the following messages repeatedly occurred in the kernel log : [3014611.640148] WARNING: at mm/vmalloc.c:1491 __vunmap+0xd3/0x100() [3014611.640269] Trying to vfree() nonexistent vm area (ffffc90000697000) With this update, the underlying source code has been fixed to initialize page pointers properly. As a result, the mm/vmalloc.c warnings no longer occur under the described circumstances. (BZ#1595600)

    description Multiple researchers have discovered a vulnerability in the way the Intel processor designs have implemented speculative execution of instructions in combination with handling of page-faults. This flaw could allow an attacker controlling an unprivileged process to read memory from arbitrary (non-user controlled) addresses, including from the kernel and all other processes running on the system or cross guest/host boundaries to read host memory. To fully resolve these vulnerabilities it is also necessary to install updated CPU microcode (only available in Debian non-free). Common server class CPUs are covered in the update released as DLA 1446-1. For Debian 8 'Jessie', these problems have been fixed in version 4.9.110-3+deb9u4~deb8u1. We recommend that you upgrade your linux-4.9 packages. NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

    NASL id CENTOS_RHSA-2018-2390.NASL
    description An update for kernel is now available for Red Hat Enterprise Linux 6. Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section. [Updated 16th August 2018] The original errata text was missing reference to CVE-2018-5390 fix. We have updated the errata text to correct this issue. No changes have been made to the packages. The kernel packages contain the Linux kernel, the core of any Linux operating system. Security Fix(es) : * Modern operating systems implement virtualization of physical memory to efficiently use available system resources and provide inter-domain protection through access control and isolation. The L1TF issue was found in the way the x86 microprocessor designs have implemented speculative execution of instructions (a commonly used performance optimisation) in combination with handling of page-faults caused by terminated virtual to physical address resolving process. As a result, an unprivileged attacker could use this flaw to read privileged memory of the kernel or other processes and/or cross guest/host boundaries to read host memory by conducting targeted cache side-channel attacks. (CVE-2018-3620, CVE-2018-3646) * An industry-wide issue was found in the way many modern microprocessor designs have implemented speculative execution of instructions past bounds check. The flaw relies on the presence of a precisely-defined instruction sequence in the privileged code and the fact that memory writes occur to an address which depends on the untrusted value. Such writes cause an update into the microprocessor's data cache even for speculatively executed instructions that never actually commit (retire). As a result, an unprivileged attacker could use this flaw to influence speculative execution and/or read privileged memory by conducting targeted cache side-channel attacks. (CVE-2018-3693) * A flaw named SegmentSmack was found in the way the Linux kernel handled specially crafted TCP packets. A remote attacker could use this flaw to trigger time and calculation expensive calls to tcp_collapse_ofo_queue() and tcp_prune_ofo_queue() functions by sending specially modified packets within ongoing TCP sessions which could lead to a CPU saturation and hence a denial of service on the system. Maintaining the denial of service condition requires continuous two-way TCP sessions to a reachable open port, thus the attacks cannot be performed using spoofed IP addresses. (CVE-2018-5390) * kernel: kvm: vmx: host GDT limit corruption (CVE-2018-10901) * kernel: Use-after-free in snd_pcm_info function in ALSA subsystem potentially leads to privilege escalation (CVE-2017-0861) * kernel: Use-after-free in snd_seq_ioctl_create_port() (CVE-2017-15265) * kernel: race condition in snd_seq_write() may lead to UAF or OOB-access (CVE-2018-7566) * kernel: Race condition in sound system can lead to denial of service (CVE-2018-1000004) For more details about the security issue(s), including the impact, a CVSS score, and other related information, refer to the CVE page(s) listed in the References section. Red Hat would like to thank Intel OSSIRT (Intel.com) for reporting CVE-2018-3620 and CVE-2018-3646; Vladimir Kiriansky (MIT) and Carl Waldspurger (Carl Waldspurger Consulting) for reporting CVE-2018-3693; Juha-Matti Tilli (Aalto University, Department of Communications and Networking and Nokia Bell Labs) for reporting CVE-2018-5390; and Vegard Nossum (Oracle Corporation) for reporting CVE-2018-10901. Bug Fix(es) : * The Least recently used (LRU) operations are batched by caching pages in per-cpu page vectors to prevent contention of the heavily used lru_lock spinlock. The page vectors can hold even the compound pages. Previously, the page vectors were cleared only if they were full. Subsequently, the amount of memory held in page vectors, which is not reclaimable, was sometimes too high. Consequently the page reclamation started the Out of Memory (OOM) killing processes. With this update, the underlying source code has been fixed to clear LRU page vectors each time when a compound page is added to them. As a result, OOM killing processes due to high amounts of memory held in page vectors no longer occur. (BZ#1575819)

    description An update for rhev-hypervisor7 is now available for RHEV 3.X Hypervisor and Agents for Red Hat Enterprise Linux 6 and RHEV 3.X Hypervisor and Agents Extended Lifecycle Support for Red Hat Enterprise Linux 7. Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section. The rhev-hypervisor7 package provides a Red Hat Enterprise Virtualization Hypervisor ISO disk image. The Red Hat Enterprise Virtualization Hypervisor is a dedicated Kernel-based Virtual Machine (KVM) hypervisor. It includes everything necessary to run and manage virtual machines: A subset of the Red Hat Enterprise Linux operating environment and the Red Hat Enterprise Virtualization Agent. Security Fix(es) : * Modern operating systems implement virtualization of physical memory to efficiently use available system resources and provide inter-domain protection through access control and isolation. The L1TF issue was found in the way the x86 microprocessor designs have implemented speculative execution of instructions (a commonly used performance optimisation) in combination with handling of page-faults caused by terminated virtual to physical address resolving process. As a result, an unprivileged attacker could use this flaw to read privileged memory of the kernel or other processes and/or cross guest/host boundaries to read host memory by conducting targeted cache side-channel attacks. (CVE-2018-3620, CVE-2018-3646) Red Hat would like to thank Intel OSSIRT (Intel.com) for reporting these issues.

    NASL id SUSE_SU-2018-2344-1.NASL
    description The SUSE Linux Enterprise 12 SP2 LTSS kernel was updated to receive various security and bugfixes. The following security bugs were fixed : - CVE-2018-3620: Local attackers on baremetal systems could use speculative code patterns on hyperthreaded processors to read data present in the L1 Datacache used by other hyperthreads on the same CPU core, potentially leaking sensitive data. (bnc#1087081). - CVE-2018-3646: Local attackers in virtualized guest systems could use speculative code patterns on hyperthreaded processors to read data present in the L1 Datacache used by other hyperthreads on the same CPU core, potentially leaking sensitive data, even from other virtual machines or the host system. (bnc#1089343). - CVE-2018-5390 aka 'SegmentSmack': The Linux Kernel can be forced to make very expensive calls to tcp_collapse_ofo_queue() and tcp_prune_ofo_queue() for every incoming packet which can lead to a denial of service (bnc#1102340). - CVE-2018-5391 aka 'FragmentSmack': A flaw in the IP packet reassembly could be used by remote attackers to consume lots of CPU time (bnc#1103097). - CVE-2018-14734: drivers/infiniband/core/ucma.c allowed ucma_leave_multicast to access a certain data structure after a cleanup step in ucma_process_join, which allowed attackers to cause a denial of service (use-after-free) (bnc#1103119). - CVE-2017-18344: The timer_create syscall implementation in kernel/time/posix-timers.c didn't properly validate the sigevent->sigev_notify field, which leads to out-of-bounds access in the show_timer function (called when /proc/$PID/timers is read). This allowed userspace applications to read arbitrary kernel memory (on a kernel built with CONFIG_POSIX_TIMERS and CONFIG_CHECKPOINT_RESTORE) (bnc#1102851 bnc#1103580). - CVE-2018-9385: When printing the 'driver_override' option from with-in the amba driver, a very long line could expose one additional uninitialized byte (bnc#1100491). - CVE-2018-13053: The alarm_timer_nsleep function in kernel/time/alarmtimer.c had an integer overflow via a large relative timeout because ktime_add_safe is not used (bnc#1099924). - CVE-2018-13405: The inode_init_owner function in fs/inode.c allowed local users to create files with an unintended group ownership, in a scenario where a directory is SGID to a certain group and is writable by a user who is not a member of that group. Here, the non-member can trigger creation of a plain file whose group ownership is that group. The intended behavior was that the non-member can trigger creation of a directory (but not a plain file) whose group ownership is that group. The non-member can escalate privileges by making the plain file executable and SGID (bnc#1100416). - CVE-2018-13406: An integer overflow in the uvesafb_setcmap function in drivers/video/fbdev/uvesafb.c could result in local attackers being able to crash the kernel or potentially elevate privileges because kmalloc_array is not used (bnc#1098016 1100418). - CVE-2018-5814: Multiple race condition errors when handling probe, disconnect, and rebind operations could be exploited to trigger a use-after-free condition or a NULL pointer dereference by sending multiple USB over IP packets (bnc#1096480). The update package also includes non-security fixes. See advisory for details. Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

It is, therefore, affected by multiple vulnerabilities : - An information disclosure vulnerability exists when the Windows kernel improperly handles objects in memory. An attacker who successfully exploited this vulnerability could obtain information to further compromise the users system. (CVE-2018-8341, CVE-2018-8348) - A remote code execution vulnerability exists when the Windows font library improperly handles specially crafted embedded fonts. An attacker who successfully exploited the vulnerability could take control of the affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. (CVE-2018-8344) - An elevation of privilege vulnerability exists in the Network Driver Interface Specification (NDIS) when ndis.sys fails to check the length of a buffer prior to copying memory to it. (CVE-2018-8343) - A remote code execution vulnerability exists in "Microsoft COM for Windows" when it fails to properly handle serialized objects. An attacker who successfully exploited the vulnerability could use a specially crafted file or script to perform actions. In an email attack scenario, an attacker could exploit the vulnerability by sending the specially crafted file to the user and convincing the user to open the file. (CVE-2018-8349) - A security feature bypass vulnerability exists when Microsoft Edge improperly handles redirect requests. The vulnerability allows Microsoft Edge to bypass Cross- Origin Resource Sharing (CORS) redirect restrictions, and to follow redirect requests that should otherwise be ignored. An attacker who successfully exploited the vulnerability could force the browser to send data that would otherwise be restricted to a destination website of the attacker's choice. (CVE-2018-8358) - A security feature bypass vulnerability exists in Device Guard that could allow an attacker to inject malicious code into a Windows PowerShell session. An attacker who successfully exploited this vulnerability could inject code into a trusted PowerShell process to bypass the Device Guard Code Integrity policy on the local machine. (CVE-2018-8200, CVE-2018-8204) - A remote code execution vulnerability exists in the way the scripting engine handles objects in memory in Microsoft browsers. The vulnerability could corrupt memory in such a way that an attacker could execute arbitrary code in the context of the current user. An attacker who successfully exploited the vulnerability could gain the same user rights as the current user. (CVE-2018-8355, CVE-2018-8372, CVE-2018-8385) - An elevation of privilege vulnerability exists in Microsoft Windows when the Windows kernel fails to properly handle parsing of certain symbolic links. An attacker who successfully exploited this vulnerability could potentially access privileged registry keys and thereby elevate permissions. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. (CVE-2018-8347) - A remote code execution vulnerability exists in Microsoft Windows that could allow remote code execution if a .LNK file is processed. An attacker who successfully exploited this vulnerability could gain the same user rights as the local user. (CVE-2018-8345) - A information disclosure vulnerability exists when WebAudio Library improperly handles audio requests. An attacker who has successfully exploited this vulnerability might be able to read privileged data across trust boundaries. In browsing scenarios, an attacker could convince a user to visit a malicious site and leverage the vulnerability to obtain privileged information from the browser process, such as sensitive data from other opened tabs. An attacker could also inject malicious code into advertising networks used by trusted sites or embed malicious code on a compromised, but trusted, site. The update addresses the vulnerability by correcting how the WebAudio Library handles audio requests. (CVE-2018-8370) - An elevation of privilege vulnerability exists in Windows when the Win32k component fails to properly handle objects in memory. An attacker who successfully exploited this vulnerability could run arbitrary code in kernel mode. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. (CVE-2018-8404) - An elevation of privilege vulnerability exists in the Windows Installer when the Windows Installer fails to properly sanitize input leading to an insecure library loading behavior. A locally authenticated attacker could run arbitrary code with elevated system privileges. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. The security update addresses the vulnerability by correcting the input sanitization error to preclude unintended elevation. (CVE-2018-8339) - A security feature bypass vulnerability exists when Active Directory Federation Services (AD FS) improperly handles multi-factor authentication requests. (CVE-2018-8340) - A remote code execution vulnerability exists in the way that the Chakra scripting engine handles objects in memory in Microsoft Edge. The vulnerability could corrupt memory in such a way that an attacker could execute arbitrary code in the context of the current user. An attacker who successfully exploited the vulnerability could gain the same user rights as the current user. (CVE-2018-8266, CVE-2018-8381) - An elevation of privilege vulnerability exists when Microsoft Cortana allows arbitrary website browsing on the lockscreen. An attacker who successfully exploited the vulnerability could steal browser stored passwords or log on to websites as another user. (CVE-2018-8253) - A remote code execution vulnerability exists when Internet Explorer improperly validates hyperlinks before loading executable libraries. An attacker who successfully exploited this vulnerability could take control of an affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. (CVE-2018-8316) - An information disclosure vulnerability exists when the Windows GDI component improperly discloses the contents of its memory. An attacker who successfully exploited the vulnerability could obtain information to further compromise the users system. There are multiple ways an attacker could exploit the vulnerability, such as by convincing a user to open a specially crafted document, or by convincing a user to visit an untrusted webpage. The security update addresses the vulnerability by correcting how the Windows GDI component handles objects in memory. (CVE-2018-8394, CVE-2018-8398) - A remote code execution vulnerability exists in the way that Microsoft browsers access objects in memory. The vulnerability could corrupt memory in a way that could allow an attacker to execute arbitrary code in the context of the current user. An attacker who successfully exploited the vulnerability could gain the same user rights as the current user. (CVE-2018-8403) - An information disclosure vulnerability exists when affected Microsoft browsers improperly allow cross-frame interaction. An attacker who successfully exploited this vulnerability could allow an attacker to obtain browser frame or window state from a different domain. For an attack to be successful, an attacker must persuade a user to open a malicious website from a secure website. This update addresses the vulnerability by denying permission to read the state of the object model, to which frames or windows on different domains should not have access. (CVE-2018-8351) - An elevation of privilege vulnerability exists in Microsoft browsers allowing sandbox escape. An attacker who successfully exploited the vulnerability could use the sandbox escape to elevate privileges on an affected system. This vulnerability by itself does not allow arbitrary code execution; however, it could allow arbitrary code to be run if the attacker uses it in combination with another vulnerability (such as a remote code execution vulnerability or another elevation of privilege vulnerability) that is capable of leveraging the elevated privileges when code execution is attempted. (CVE-2018-8357) - An Elevation of Privilege vulnerability exists when Diagnostics Hub Standard Collector allows file creation in arbitrary locations. (CVE-2018-0952) - A remote code execution vulnerability exists in the way that the scripting engine handles objects in memory in Internet Explorer. The vulnerability could corrupt memory in such a way that an attacker could execute arbitrary code in the context of the current user. An attacker who successfully exploited the vulnerability could gain the same user rights as the current user. (CVE-2018-8353, CVE-2018-8371, CVE-2018-8373, CVE-2018-8389) - An elevation of privilege vulnerability exists when the DirectX Graphics Kernel (DXGKRNL) driver improperly handles objects in memory. An attacker who successfully exploited this vulnerability could run processes in an elevated context. (CVE-2018-8401, CVE-2018-8405, CVE-2018-8406) - An information disclosure vulnerability exists in Microsoft .NET Framework that could allow an attacker to access information in multi-tenant environments. The vulnerability is caused when .NET Framework is used in high-load/high-density network connections where content from one stream can blend into another stream. (CVE-2018-8360) - A spoofing vulnerability exists when Microsoft Edge improperly handles specific HTML content. An attacker who successfully exploited this vulnerability could trick a user into believing that the user was on a legitimate website. The specially crafted website could either spoof content or serve as a pivot to chain an attack with other vulnerabilities in web services. (CVE-2018-8388)

(CVE-2018-8343) - An information disclosure vulnerability exists when the Windows GDI component improperly discloses the contents of its memory. An attacker who successfully exploited the vulnerability could obtain information to further compromise the users system. There are multiple ways an attacker could exploit the vulnerability, such as by convincing a user to open a specially crafted document, or by convincing a user to visit an untrusted webpage. The security update addresses the vulnerability by correcting how the Windows GDI component handles objects in memory. (CVE-2018-8394, CVE-2018-8398) - A remote code execution vulnerability exists in "Microsoft COM for Windows" when it fails to properly handle serialized objects. An attacker who successfully exploited the vulnerability could use a specially crafted file or script to perform actions. In an email attack scenario, an attacker could exploit the vulnerability by sending the specially crafted file to the user and convincing the user to open the file. (CVE-2018-8349) - An elevation of privilege vulnerability exists in the Windows Installer when the Windows Installer fails to properly sanitize input leading to an insecure library loading behavior. A locally authenticated attacker could run arbitrary code with elevated system privileges. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. The security update addresses the vulnerability by correcting the input sanitization error to preclude unintended elevation. (CVE-2018-8339) - An information disclosure vulnerability exists in Microsoft .NET Framework that could allow an attacker to access information in multi-tenant environments. The vulnerability is caused when .NET Framework is used in high-load/high-density network connections where content from one stream can blend into another stream. (CVE-2018-8360) - An information disclosure vulnerability exists when affected Microsoft browsers improperly allow cross-frame interaction. An attacker who successfully exploited this vulnerability could allow an attacker to obtain browser frame or window state from a different domain. For an attack to be successful, an attacker must persuade a user to open a malicious website from a secure website. This update addresses the vulnerability by denying permission to read the state of the object model, to which frames or windows on different domains should not have access. (CVE-2018-8351)

    description An update for kernel is now available for Red Hat Enterprise Linux 6.4 Advanced Update Support. Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section. The kernel packages contain the Linux kernel, the core of any Linux operating system. Security Fix(es) : * Modern operating systems implement virtualization of physical memory to efficiently use available system resources and provide inter-domain protection through access control and isolation. The L1TF issue was found in the way the x86 microprocessor designs have implemented speculative execution of instructions (a commonly used performance optimisation) in combination with handling of page-faults caused by terminated virtual to physical address resolving process. As a result, an unprivileged attacker could use this flaw to read privileged memory of the kernel or other processes and/or cross guest/host boundaries to read host memory by conducting targeted cache side-channel attacks. (CVE-2018-3620, CVE-2018-3646) * An industry-wide issue was found in the way many modern microprocessor designs have implemented speculative execution of Load & Store instructions (a commonly used performance optimization). It relies on the presence of a precisely-defined instruction sequence in the privileged code as well as the fact that memory read from address to which a recent memory write has occurred may see an older value and subsequently cause an update into the microprocessor's data cache even for speculatively executed instructions that never actually commit (retire). As a result, an unprivileged attacker could use this flaw to read privileged memory by conducting targeted cache side-channel attacks. (CVE-2018-3639) * kernel: kvm: vmx: host GDT limit corruption (CVE-2018-10901) For more details about the security issue(s), including the impact, a CVSS score, and other related information, refer to the CVE page(s) listed in the References section. Red Hat would like to thank Intel OSSIRT (Intel.com) for reporting CVE-2018-3620 and CVE-2018-3646; Ken Johnson (Microsoft Security Response Center) and Jann Horn (Google Project Zero) for reporting CVE-2018-3639; and Vegard Nossum (Oracle Corporation) for reporting CVE-2018-10901.

  • NASL family SuSE Local Security Checks
    NASL id SUSE_SU-2018-2344-2.NASL
    description The SUSE Linux Enterprise 12 SP2 LTSS kernel was updated to receive various security and bugfixes. The following security bugs were fixed : CVE-2018-3620: Local attackers on baremetal systems could use speculative code patterns on hyperthreaded processors to read data present in the L1 Datacache used by other hyperthreads on the same CPU core, potentially leaking sensitive data. (bnc#1087081). CVE-2018-3646: Local attackers in virtualized guest systems could use speculative code patterns on hyperthreaded processors to read data present in the L1 Datacache used by other hyperthreads on the same CPU core, potentially leaking sensitive data, even from other virtual machines or the host system. (bnc#1089343). CVE-2018-5390 aka 'SegmentSmack': The Linux Kernel can be forced to make very expensive calls to tcp_collapse_ofo_queue() and tcp_prune_ofo_queue() for every incoming packet which can lead to a denial of service (bnc#1102340). CVE-2018-5391 aka 'FragmentSmack': A flaw in the IP packet reassembly could be used by remote attackers to consume lots of CPU time (bnc#1103097). CVE-2018-14734: drivers/infiniband/core/ucma.c allowed ucma_leave_multicast to access a certain data structure after a cleanup step in ucma_process_join, which allowed attackers to cause a denial of service (use-after-free) (bnc#1103119). CVE-2017-18344: The timer_create syscall implementation in kernel/time/posix-timers.c didn't properly validate the sigevent->sigev_notify field, which leads to out-of-bounds access in the show_timer function (called when /proc/$PID/timers is read). This allowed userspace applications to read arbitrary kernel memory (on a kernel built with CONFIG_POSIX_TIMERS and CONFIG_CHECKPOINT_RESTORE) (bnc#1102851 bnc#1103580). CVE-2018-9385: When printing the 'driver_override' option from with-in the amba driver, a very long line could expose one additional uninitialized byte (bnc#1100491). CVE-2018-13053: The alarm_timer_nsleep function in kernel/time/alarmtimer.c had an integer overflow via a large relative timeout because ktime_add_safe is not used (bnc#1099924). CVE-2018-13405: The inode_init_owner function in fs/inode.c allowed local users to create files with an unintended group ownership, in a scenario where a directory is SGID to a certain group and is writable by a user who is not a member of that group. Here, the non-member can trigger creation of a plain file whose group ownership is that group. The intended behavior was that the non-member can trigger creation of a directory (but not a plain file) whose group ownership is that group. The non-member can escalate privileges by making the plain file executable and SGID (bnc#1100416). CVE-2018-13406: An integer overflow in the uvesafb_setcmap function in drivers/video/fbdev/uvesafb.c could result in local attackers being able to crash the kernel or potentially elevate privileges because kmalloc_array is not used (bnc#1098016 1100418). CVE-2018-5814: Multiple race condition errors when handling probe, disconnect, and rebind operations could be exploited to trigger a use-after-free condition or a NULL pointer dereference by sending multiple USB over IP packets (bnc#1096480). The update package also includes non-security fixes. See advisory for details. Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

An attacker who successfully exploited the vulnerability could gain the same user rights as the current user. (CVE-2018-8403) - An information disclosure vulnerability exists when the Windows kernel improperly handles objects in memory. An attacker who successfully exploited this vulnerability could obtain information to further compromise the users system. (CVE-2018-8341, CVE-2018-8348) - A remote code execution vulnerability exists when the Windows font library improperly handles specially crafted embedded fonts. An attacker who successfully exploited the vulnerability could take control of the affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. (CVE-2018-8344) - An elevation of privilege vulnerability exists in Windows when the Win32k component fails to properly handle objects in memory. An attacker who successfully exploited this vulnerability could run arbitrary code in kernel mode. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. (CVE-2018-8404) - A remote code execution vulnerability exists when Internet Explorer improperly validates hyperlinks before loading executable libraries. An attacker who successfully exploited this vulnerability could take control of an affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. (CVE-2018-8316) - A security feature bypass vulnerability exists in Device Guard that could allow an attacker to inject malicious code into a Windows PowerShell session. An attacker who successfully exploited this vulnerability could inject code into a trusted PowerShell process to bypass the Device Guard Code Integrity policy on the local machine. (CVE-2018-8200, CVE-2018-8204) - An Elevation of Privilege vulnerability exists when Diagnostics Hub Standard Collector allows file creation in arbitrary locations. (CVE-2018-0952) - A remote code execution vulnerability exists in the way the scripting engine handles objects in memory in Microsoft browsers. The vulnerability could corrupt memory in such a way that an attacker could execute arbitrary code in the context of the current user.

(CVE-2018-8353, CVE-2018-8371, CVE-2018-8373, CVE-2018-8389) - A remote code execution vulnerability exists in Microsoft Windows that could allow remote code execution if a .LNK file is processed. An attacker who successfully exploited this vulnerability could gain the same user rights as the local user. (CVE-2018-8345) - An elevation of privilege vulnerability exists when the DirectX Graphics Kernel (DXGKRNL) driver improperly handles objects in memory. An attacker who successfully exploited this vulnerability could run processes in an elevated context. (CVE-2018-8401, CVE-2018-8405, CVE-2018-8406) - A information disclosure vulnerability exists when WebAudio Library improperly handles audio requests. An attacker who has successfully exploited this vulnerability might be able to read privileged data across trust boundaries. In browsing scenarios, an attacker could convince a user to visit a malicious site and leverage the vulnerability to obtain privileged information from the browser process, such as sensitive data from other opened tabs. An attacker could also inject malicious code into advertising networks used by trusted sites or embed malicious code on a compromised, but trusted, site. The update addresses the vulnerability by correcting how the WebAudio Library handles audio requests. (CVE-2018-8370) - An elevation of privilege vulnerability exists in the Network Driver Interface Specification (NDIS) when ndis.sys fails to check the length of a buffer prior to copying memory to it. (CVE-2018-8343) - An information disclosure vulnerability exists when the Windows GDI component improperly discloses the contents of its memory. An attacker who successfully exploited the vulnerability could obtain information to further compromise the users system. There are multiple ways an attacker could exploit the vulnerability, such as by convincing a user to open a specially crafted document, or by convincing a user to visit an untrusted webpage.

An attacker who successfully exploited the vulnerability could use a specially crafted file or script to perform actions. In an email attack scenario, an attacker could exploit the vulnerability by sending the specially crafted file to the user and convincing the user to open the file. (CVE-2018-8349) - An elevation of privilege vulnerability exists in the Windows Installer when the Windows Installer fails to properly sanitize input leading to an insecure library loading behavior. A locally authenticated attacker could run arbitrary code with elevated system privileges. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. The security update addresses the vulnerability by correcting the input sanitization error to preclude unintended elevation. (CVE-2018-8339) - An information disclosure vulnerability exists in Microsoft .NET Framework that could allow an attacker to access information in multi-tenant environments. The vulnerability is caused when .NET Framework is used in high-load/high-density network connections where content from one stream can blend into another stream. (CVE-2018-8360) - An information disclosure vulnerability exists when affected Microsoft browsers improperly allow cross-frame interaction. An attacker who successfully exploited this vulnerability could allow an attacker to obtain browser frame or window state from a different domain. For an attack to be successful, an attacker must persuade a user to open a malicious website from a secure website. This update addresses the vulnerability by denying permission to read the state of the object model, to which frames or windows on different domains should not have access. (CVE-2018-8351) - An elevation of privilege vulnerability exists in Microsoft browsers allowing sandbox escape. An attacker who successfully exploited the vulnerability could use the sandbox escape to elevate privileges on an affected system. This vulnerability by itself does not allow arbitrary code execution; however, it could allow arbitrary code to be run if the attacker uses it in combination with another vulnerability (such as a remote code execution vulnerability or another elevation of privilege vulnerability) that is capable of leveraging the elevated privileges when code execution is attempted.
