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 An update for kernel-rt is now available for Red Hat Enterprise Linux 7. Red Hat Product Security has rated this update as having a security impact of Moderate. 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-rt packages provide the Real Time Linux Kernel, which enables fine-tuning for systems with extremely high determinism requirements. Security Fix(es) : * It was found that the timer functionality in the Linux kernel ALSA subsystem is prone to a race condition between read and ioctl system call handlers, resulting in an uninitialized memory disclosure to user space. A local user could use this flaw to read information belonging to other users. (CVE-2017-1000380, Moderate) Red Hat would like to thank Alexander Potapenko (Google) for reporting this issue. Bug Fix(es) : * The kernel-rt packages have been upgraded to the 3.10.0-693.11.1 source tree, which provides a number of bug fixes over the previous version. (BZ# 1500035) * Previously, the hfi1 driver called the preempt_disable() function to prevent migration on standard Red Hat Enterprise Linux and on Red Hat Enterprise Linux for Real Time. On Red Hat Enterprise Linux for Real Time with the realtime kernel (kernel-rt), calling preempt_disable() triggered a kernel panic. With this update, the kernel-rt code has been modified to use a realtime-specific function call to the preempt_disable_nort() function, which expands to the correct calls based on the kernel that is running. As a result, the hfi1 driver now works correctly on both Red Hat Enterprise Linux kernel and Red Hat Enterprise Linux for Real Time kernel-rt. (BZ# 1507053) * Previously, the hfi1 driver called the preempt_disable() function to prevent migration on standard Red Hat Enterprise Linux and on Red Hat Enterprise Linux for Real Time. On Red Hat Enterprise Linux for Real Time with the realtime kernel (kernel-rt), calling preempt_disable() triggered a kernel panic. With this update, the kernel-rt code has been modified to use a realtime-specific function call to the preempt_disable_nort() function, which expands to the correct calls based on the kernel that is running. As a result, the hfi1 driver now works correctly on both Red Hat Enterprise Linux kernel and Red Hat Enterprise Linux for Real Time kernel-rt. (BZ# 1507054) * In the realtime kernel, if the rt_mutex locking mechanism was taken in the interrupt context, the normal priority inheritance protocol incorrectly identified a deadlock, and a kernel panic occurred. This update reverts the patch that added rt_mutex in the interrupt context, and the kernel no longer panics due to this behavior. (BZ#1511382) Enhancement(s) : * The current realtime throttling mechanism prevents the starvation of non-realtime tasks by CPU-intensive realtime tasks. When a realtime run queue is throttled, it allows non-realtime tasks to run. If there are not non-realtime tasks, the CPU goes idle. To safely maximize CPU usage by decreasing the CPU idle time, the RT_RUNTIME_GREED scheduler feature has been implemented. When enabled, this feature checks if non-realtime tasks are starving before throttling the realtime task. The RT_RUNTIME_GREED scheduler option guarantees some run time on all CPUs for the non-realtime tasks, while keeping the realtime tasks running as much as possible. (BZ# 1505158)

    description Several vulnerabilities have been discovered in the Linux kernel that may lead to privilege escalation, denial of service or information leaks. - CVE-2017-7518 Andy Lutomirski discovered that KVM is prone to an incorrect debug exception (#DB) error occurring while emulating a syscall instruction. A process inside a guest can take advantage of this flaw for privilege escalation inside a guest. - CVE-2017-7558 (stretch only) Stefano Brivio of Red Hat discovered that the SCTP subsystem is prone to a data leak vulnerability due to an out-of-bounds read flaw, allowing to leak up to 100 uninitialized bytes to userspace. - CVE-2017-10661 (jessie only) Dmitry Vyukov of Google reported that the timerfd facility does not properly handle certain concurrent operations on a single file descriptor. This allows a local attacker to cause a denial of service or potentially execute arbitrary code. - CVE-2017-11600 Bo Zhang reported that the xfrm subsystem does not properly validate one of the parameters to a netlink message. Local users with the CAP_NET_ADMIN capability can use this to cause a denial of service or potentially to execute arbitrary code. - CVE-2017-12134 / #866511 / XSA-229 Jan H. Schoenherr of Amazon discovered that when Linux is running in a Xen PV domain on an x86 system, it may incorrectly merge block I/O requests. A buggy or malicious guest may trigger this bug in dom0 or a PV driver domain, causing a denial of service or potentially execution of arbitrary code. This issue can be mitigated by disabling merges on the underlying back-end block devices, e.g.:echo 2 > /sys/block/nvme0n1/queue/nomerges - CVE-2017-12146 (stretch only) Adrian Salido of Google reported a race condition in access to the'driver_override' attribute for platform devices in sysfs. If unprivileged users are permitted to access this attribute, this might allow them to gain privileges. - CVE-2017-12153 Bo Zhang reported that the cfg80211 (wifi) subsystem does not properly validate the parameters to a netlink message. Local users with the CAP_NET_ADMIN capability (in any user namespace with a wifi device) can use this to cause a denial of service. - CVE-2017-12154 Jim Mattson of Google reported that the KVM implementation for Intel x86 processors did not correctly handle certain nested hypervisor configurations. A malicious guest (or nested guest in a suitable L1 hypervisor) could use this for denial of service. - CVE-2017-14106 Andrey Konovalov discovered that a user-triggerable division by zero in the tcp_disconnect() function could result in local denial of service. - CVE-2017-14140 Otto Ebeling reported that the move_pages() system call performed insufficient validation of the UIDs of the calling and target processes, resulting in a partial ASLR bypass. This made it easier for local users to exploit vulnerabilities in programs installed with the set-UID permission bit set. - CVE-2017-14156 'sohu0106' reported an information leak in the atyfb video driver. A local user with access to a framebuffer device handled by this driver could use this to obtain sensitive information. - CVE-2017-14340 Richard Wareing discovered that the XFS implementation allows the creation of files with the 'realtime' flag on a filesystem with no realtime device, which can result in a crash (oops). A local user with access to an XFS filesystem that does not have a realtime device can use this for denial of service. - CVE-2017-14489 ChunYu Wang of Red Hat discovered that the iSCSI subsystem does not properly validate the length of a netlink message, leading to memory corruption. A local user with permission to manage iSCSI devices can use this for denial of service or possibly to execute arbitrary code. - CVE-2017-14497 (stretch only) Benjamin Poirier of SUSE reported that vnet headers are not properly handled within the tpacket_rcv() function in the raw packet (af_packet) feature. A local user with the CAP_NET_RAW capability can take advantage of this flaw to cause a denial of service (buffer overflow, and disk and memory corruption) or have other impact. - CVE-2017-1000111 Andrey Konovalov of Google reported a race condition in the raw packet (af_packet) feature. Local users with the CAP_NET_RAW capability can use this for denial of service or possibly to execute arbitrary code. - CVE-2017-1000112 Andrey Konovalov of Google reported a race condition flaw in the UDP Fragmentation Offload (UFO) code. A local user can use this flaw for denial of service or possibly to execute arbitrary code. - CVE-2017-1000251 / #875881 Armis Labs discovered that the Bluetooth subsystem does not properly validate L2CAP configuration responses, leading to a stack-based buffer overflow. This is one of several vulnerabilities dubbed 'Blueborne'. A nearby attacker can use this to cause a denial of service or possibly to execute arbitrary code on a system with Bluetooth enabled. - CVE-2017-1000252 (stretch only) Jan H. Schoenherr of Amazon reported that the KVM implementation for Intel x86 processors did not correctly validate interrupt injection requests. A local user with permission to use KVM could use this for denial of service. - CVE-2017-1000370 The Qualys Research Labs reported that a large argument or environment list can result in ASLR bypass for 32-bit PIE binaries. - CVE-2017-1000371 The Qualys Research Labs reported that a large argument or environment list can result in a stack/heap clash for 32-bit PIE binaries. - CVE-2017-1000380 Alexander Potapenko of Google reported a race condition in the ALSA (sound) timer driver, leading to an information leak. A local user with permission to access sound devices could use this to obtain sensitive information. Debian disables unprivileged user namespaces by default, but if they are enabled (via the kernel.unprivileged_userns_clone sysctl) then CVE-2017-11600, CVE-2017-14497 and CVE-2017-1000111 can be exploited by any local user.

  • NASL family Red Hat Local Security Checks
    NASL id REDHAT-RHSA-2017-3295.NASL
    description An update for kernel-rt is now available for Red Hat Enterprise MRG 2. Red Hat Product Security has rated this update as having a security impact of Moderate. 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-rt packages provide the Real Time Linux Kernel, which enables fine-tuning for systems with extremely high determinism requirements. Security Fix(es) : * It was found that the timer functionality in the Linux kernel ALSA subsystem is prone to a race condition between read and ioctl system call handlers, resulting in an uninitialized memory disclosure to user space. A local user could use this flaw to read information belonging to other users. (CVE-2017-1000380, Moderate) Red Hat would like to thank Alexander Potapenko (Google) for reporting this issue. Bug Fix(es) : * The current realtime throttling mechanism prevents the starvation of non-realtime tasks by CPU-intensive realtime tasks. When a realtime run queue is throttled, it allows non-realtime tasks to run. If there are not non-realtime tasks, the CPU goes idle. To safely maximize CPU usage by decreasing the CPU idle time, the RT_RUNTIME_GREED scheduler feature has been implemented. When enabled, this feature checks if non-realtime tasks are starving before throttling the realtime task. The RT_RUNTIME_GREED scheduler option guarantees some run time on all CPUs for the non-realtime tasks, while keeping the realtime tasks running as much as possible. (BZ# 1459275) * The kernel-rt packages have been upgraded to version 3.10.0-693.11.1.rt56.595, which provides a number of security and bug fixes over the previous version. (BZ#1500036) * In the realtime kernel, if the rt_mutex locking mechanism was taken in the interrupt context, the normal priority inheritance protocol incorrectly identified a deadlock, and a kernel panic occurred. This update reverts the patch that added rt_mutex in the interrupt context, and the kernel no longer panics due to this behavior. (BZ#1509021)

(CVE-2014-9900) It was discovered that the Linux kernel did not properly restrict access to /proc/iomem. A local attacker could use this to expose sensitive information. (CVE-2015-8944) Alexander Potapenko discovered a race condition in the Advanced Linux Sound Architecture (ALSA) subsystem in the Linux kernel. A local attacker could use this to expose sensitive information (kernel memory). (CVE-2017-1000380) Li Qiang discovered that the DRM driver for VMware Virtual GPUs in the Linux kernel did not properly validate some ioctl arguments. A local attacker could use this to cause a denial of service (system crash). (CVE-2017-7346) Jann Horn discovered that bpf in Linux kernel does not restrict the output of the print_bpf_insn function. A local attacker could use this to obtain sensitive address information. (CVE-2017-9150) Murray McAllister discovered that the DRM driver for VMware Virtual GPUs in the Linux kernel did not properly initialize memory. A local attacker could use this to expose sensitive information (kernel memory). (CVE-2017-9605).

(bnc#1039354). - CVE-2017-1000380: sound/core/timer.c in the Linux kernel is vulnerable to a data race in the ALSA /dev/snd/timer driver resulting in local users being able to read information belonging to other users, i.e., uninitialized memory contents may be disclosed when a read and an ioctl happen at the same time (bnc#1044125). - CVE-2017-7346: The vmw_gb_surface_define_ioctl function in drivers/gpu/drm/vmwgfx/vmwgfx_surface.c in the Linux kernel did not validate certain levels data, which allowed local users to cause a denial of service (system hang) via a crafted ioctl call for a /dev/dri/renderD* device (bnc#1031796). - CVE-2017-9242: The __ip6_append_data function in net/ipv6/ip6_output.c in the Linux kernel is too late in checking whether an overwrite of an skb data structure may occur, which allowed local users to cause a denial of service (system crash) via crafted system calls (bnc#1041431). - CVE-2017-9076: The dccp_v6_request_recv_sock function in net/dccp/ipv6.c in the Linux kernel mishandled inheritance, which allowed local users to cause a denial of service or possibly have unspecified other impact via crafted system calls, a related issue to CVE-2017-8890 (bnc#1039885). - CVE-2017-9077: The tcp_v6_syn_recv_sock function in net/ipv6/tcp_ipv6.c in the Linux kernel mishandled inheritance, which allowed local users to cause a denial of service or possibly have unspecified other impact via crafted system calls, a related issue to CVE-2017-8890 (bnc#1040069). - CVE-2017-9075: The sctp_v6_create_accept_sk function in net/sctp/ipv6.c in the Linux kernel mishandled inheritance, which allowed local users to cause a denial of service or possibly have unspecified other impact via crafted system calls, a related issue to CVE-2017-8890 (bnc#1039883). - CVE-2017-9074: The IPv6 fragmentation implementation in the Linux kernel did not consider that the nexthdr field may be associated with an invalid option, which allowed local users to cause a denial of service (out-of-bounds read and BUG) or possibly have unspecified other impact via crafted socket and send system calls (bnc#1039882). - CVE-2017-8924: The edge_bulk_in_callback function in drivers/usb/serial/io_ti.c in the Linux kernel allowed local users to obtain sensitive information (in the dmesg ringbuffer and syslog) from uninitialized kernel memory by using a crafted USB device (posing as an io_ti USB serial device) to trigger an integer underflow. (bsc#1038982) - CVE-2017-8925: The omninet_open function in drivers/usb/serial/omninet.c in the Linux kernel allowed local users to cause a denial of service (tty exhaustion) by leveraging reference count mishandling. (bsc#1038981) - CVE-2017-7487: The ipxitf_ioctl function in net/ipx/af_ipx.c in the Linux kernel mishandled reference counts, which allowed local users to cause a denial of service (use-after-free) or possibly have unspecified other impact via a failed SIOCGIFADDR ioctl call for an IPX interface (bnc#1038879). - CVE-2017-8890: The inet_csk_clone_lock function in net/ipv4/inet_connection_sock.c in the Linux kernel allowed attackers to cause a denial of service (double free) or possibly have unspecified other impact by leveraging use of the accept system call (bnc#1038544). - CVE-2017-9150: The do_check function in kernel/bpf/verifier.c in the Linux kernel did not make the allow_ptr_leaks value available for restricting the output of the print_bpf_insn function, which allowed local users to obtain sensitive address information via crafted bpf system calls (bnc#1040279). - CVE-2017-7618: crypto/ahash.c in the Linux kernel allowed attackers to cause a denial of service (API operation calling its own callback, and infinite recursion) by triggering EBUSY on a full queue (bnc#1033340). - CVE-2017-7616: Incorrect error handling in the set_mempolicy and mbind compat syscalls in mm/mempolicy.c in the Linux kernel allowed local users to obtain sensitive information from uninitialized stack data by triggering failure of a certain bitmap operation (bnc#1033336). 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.

  • NASL family Debian Local Security Checks
    NASL id DEBIAN_DLA-1099.NASL
    description Several vulnerabilities have been discovered in the Linux kernel that may lead to a privilege escalation, denial of service or information leaks. CVE-2017-7482 Shi Lei discovered that RxRPC Kerberos 5 ticket handling code does not properly verify metadata, leading to information disclosure, denial of service or potentially execution of arbitrary code. CVE-2017-7542 An integer overflow vulnerability in the ip6_find_1stfragopt() function was found allowing a local attacker with privileges to open raw sockets to cause a denial of service. CVE-2017-7889 Tommi Rantala and Brad Spengler reported that the mm subsystem does not properly enforce the CONFIG_STRICT_DEVMEM protection mechanism, allowing a local attacker with access to /dev/mem to obtain sensitive information or potentially execute arbitrary code. CVE-2017-10661 Dmitry Vyukov of Google reported that the timerfd facility does not properly handle certain concurrent operations on a single file descriptor. This allows a local attacker to cause a denial of service or potentially to execute arbitrary code. CVE-2017-10911 / XSA-216 Anthony Perard of Citrix discovered an information leak flaw in Xen blkif response handling, allowing a malicious unprivileged guest to obtain sensitive information from the host or other guests. CVE-2017-11176 It was discovered that the mq_notify() function does not set the sock pointer to NULL upon entry into the retry logic. An attacker can take advantage of this flaw during a userspace close of a Netlink socket to cause a denial of service or potentially cause other impact. CVE-2017-11600 bo Zhang reported that the xfrm subsystem does not properly validate one of the parameters to a netlink message. Local users with the CAP_NET_ADMIN capability can use this to cause a denial of service or potentially to execute arbitrary code. CVE-2017-12134 / #866511 / XSA-229 Jan H. Schönherr of Amazon discovered that when Linux is running in a Xen PV domain on an x86 system, it may incorrectly merge block I/O requests. A buggy or malicious guest may trigger this bug in dom0 or a PV driver domain, causing a denial of service or potentially execution of arbitrary code. This issue can be mitigated by disabling merges on the underlying back-end block devices, e.g.: echo 2 > /sys/block/nvme0n1/queue/nomerges CVE-2017-12153 bo Zhang reported that the cfg80211 (wifi) subsystem does not properly validate the parameters to a netlink message. Local users with the CAP_NET_ADMIN capability on a system with a wifi device can use this to cause a denial of service. CVE-2017-12154 Jim Mattson of Google reported that the KVM implementation for Intel x86 processors did not correctly handle certain nested hypervisor configurations. A malicious guest (or nested guest in a suitable L1 hypervisor) could use this for denial of service. CVE-2017-14106 Andrey Konovalov of Google reported that a specific sequence of operations on a TCP socket could lead to division by zero. A local user could use this for denial of service. CVE-2017-14140 Otto Ebeling reported that the move_pages() system call permitted users to discover the memory layout of a set-UID process running under their real user-ID. This made it easier for local users to exploit vulnerabilities in programs installed with the set-UID permission bit set. CVE-2017-14156 'sohu0106' reported an information leak in the atyfb video driver. A local user with access to a framebuffer device handled by this driver could use this to obtain sensitive information. CVE-2017-14340 Richard Wareing discovered that the XFS implementation allows the creation of files with the 'realtime' flag on a filesystem with no realtime device, which can result in a crash (oops). A local user with access to an XFS filesystem that does not have a realtime device can use this for denial of service. CVE-2017-14489 ChunYu of Red Hat discovered that the iSCSI subsystem does not properly validate the length of a netlink message, leading to memory corruption. A local user with permission to manage iSCSI devices can use this for denial of service or possibly to execute arbitrary code. CVE-2017-1000111 Andrey Konovalov of Google reported that a race condition in the raw packet (af_packet) feature. Local users with the CAP_NET_RAW capability can use this to cause a denial of service or possibly to execute arbitrary code. CVE-2017-1000251 / #875881 Armis Labs discovered that the Bluetooth subsystem does not properly validate L2CAP configuration responses, leading to a stack buffer overflow. This is one of several vulnerabilities dubbed 'Blueborne'. A nearby attacker can use this to cause a denial of service or possibly to execute arbitrary code on a system with Bluetooth enabled. CVE-2017-1000363 Roee Hay reported that the lp driver does not properly bounds-check passed arguments. This has no security impact in Debian. CVE-2017-1000365 It was discovered that argument and environment pointers are not properly taken into account by the size restrictions on arguments and environmental strings passed through execve(). A local attacker can take advantage of this flaw in conjunction with other flaws to execute arbitrary code. CVE-2017-1000380 Alexander Potapenko of Google reported a race condition in the ALSA (sound) timer driver, leading to an information leak. A local user with permission to access sound devices could use this to obtain sensitive information. For Debian 7 'Wheezy', these problems have been fixed in version 3.2.93-1. This version also includes bug fixes from upstream versions up to and including 3.2.93. For Debian 8 'Jessie', these problems have been fixed in version 3.16.43-2+deb8u4 or were fixed in an earlier version. For Debian 9 'Stretch', these problems have been fixed in version 4.9.30-2+deb9u4 or were fixed in an earlier version. We recommend that you upgrade your linux packages.

    NASL id SUSE_SU-2017-2920-1.NASL
    description The SUSE Linux Enterprise 12 GA LTS kernel was updated to receive various security and bugfixes. The following security bugs were fixed : - CVE-2017-15649: net/packet/af_packet.c in the Linux kernel allowed local users to gain privileges via crafted system calls that trigger mishandling of packet_fanout data structures, because of a race condition (involving fanout_add and packet_do_bind) that leads to a use-after-free, a different vulnerability than CVE-2017-6346 (bnc#1064388). - CVE-2015-9004: kernel/events/core.c in the Linux kernel mishandled counter grouping, which allowed local users to gain privileges via a crafted application, related to the perf_pmu_register and perf_event_open functions (bnc#1037306). - CVE-2016-10229: udp.c in the Linux kernel allowed remote attackers to execute arbitrary code via UDP traffic that triggers an unsafe second checksum calculation during execution of a recv system call with the MSG_PEEK flag (bnc#1032268). - CVE-2016-9604: The handling of keyrings starting with '.' in KEYCTL_JOIN_SESSION_KEYRING, which could have allowed local users to manipulate privileged keyrings, was fixed (bsc#1035576) - CVE-2017-1000363: Linux drivers/char/lp.c Out-of-Bounds Write. Due to a missing bounds check, and the fact that parport_ptr integer is static, a 'secure boot' kernel command line adversary (can happen due to bootloader vulns, e.g. Google Nexus 6's CVE-2016-10277, where due to a vulnerability the adversary has partial control over the command line) can overflow the parport_nr array in the following code, by appending many (>LP_NO) 'lp=none' arguments to the command line (bnc#1039456). - CVE-2017-1000365: The Linux Kernel imposes a size restriction on the arguments and environmental strings passed through RLIMIT_STACK/RLIM_INFINITY (1/4 of the size), but did not take the argument and environment pointers into account, which allowed attackers to bypass this limitation. (bnc#1039354). - CVE-2017-1000380: sound/core/timer.c in the Linux kernel is vulnerable to a data race in the ALSA /dev/snd/timer driver resulting in local users being able to read information belonging to other users, i.e., uninitialized memory contents may be disclosed when a read and an ioctl happen at the same time (bnc#1044125). - CVE-2017-10661: Race condition in fs/timerfd.c in the Linux kernel allowed local users to gain privileges or cause a denial of service (list corruption or use-after-free) via simultaneous file-descriptor operations that leverage improper might_cancel queueing (bnc#1053152). - CVE-2017-11176: The mq_notify function in the Linux kernel did not set the sock pointer to NULL upon entry into the retry logic. During a user-space close of a Netlink socket, it allowed attackers to cause a denial of service (use-after-free) or possibly have unspecified other impact (bnc#1048275). - CVE-2017-12153: A security flaw was discovered in the nl80211_set_rekey_data() function in net/wireless/nl80211.c in the Linux kernel This function did not check whether the required attributes are present in a Netlink request. This request can be issued by a user with the CAP_NET_ADMIN capability and may result in a NULL pointer dereference and system crash (bnc#1058410). - CVE-2017-12154: The prepare_vmcs02 function in arch/x86/kvm/vmx.c in the Linux kernel did not ensure that the 'CR8-load exiting' and 'CR8-store exiting' L0 vmcs02 controls exist in cases where L1 omits the 'use TPR shadow' vmcs12 control, which allowed KVM L2 guest OS users to obtain read and write access to the hardware CR8 register (bnc#1058507). - CVE-2017-12762: In /drivers/isdn/i4l/isdn_net.c: A user-controlled buffer is copied into a local buffer of constant size using strcpy without a length check which can cause a buffer overflow. (bnc#1053148). - CVE-2017-13080: Wi-Fi Protected Access (WPA and WPA2) allowed reinstallation of the Group Temporal Key (GTK) during the group key handshake, allowing an attacker within radio range to replay frames from access points to clients (bnc#1063667). - CVE-2017-14051: An integer overflow in the qla2x00_sysfs_write_optrom_ctl function in drivers/scsi/qla2xxx/qla_attr.c in the Linux kernel allowed local users to cause a denial of service (memory corruption and system crash) by leveraging root access (bnc#1056588). - CVE-2017-14106: The tcp_disconnect function in net/ipv4/tcp.c in the Linux kernel allowed local users to cause a denial of service (__tcp_select_window divide-by-zero error and system crash) by triggering a disconnect within a certain tcp_recvmsg code path (bnc#1056982). - CVE-2017-14140: The move_pages system call in mm/migrate.c in the Linux kernel doesn't check the effective uid of the target process, enabling a local attacker to learn the memory layout of a setuid executable despite ASLR (bnc#1057179). - CVE-2017-15265: Use-after-free vulnerability in the Linux kernel allowed local users to have unspecified impact via vectors related to /dev/snd/seq (bnc#1062520). - CVE-2017-15274: security/keys/keyctl.c in the Linux kernel did not consider the case of a NULL payload in conjunction with a nonzero length value, which allowed local users to cause a denial of service (NULL pointer dereference and OOPS) via a crafted add_key or keyctl system call, a different vulnerability than CVE-2017-12192 (bnc#1045327). - CVE-2017-2647: The KEYS subsystem in the Linux kernel allowed local users to gain privileges or cause a denial of service (NULL pointer dereference and system crash) via vectors involving a NULL value for a certain match field, related to the keyring_search_iterator function in keyring.c (bnc#1030593). - CVE-2017-6951: The keyring_search_aux function in security/keys/keyring.c in the Linux kernel allowed local users to cause a denial of service (NULL pointer dereference and OOPS) via a request_key system call for the 'dead' type (bnc#1029850). - CVE-2017-7482: A potential memory corruption was fixed in decoding of krb5 principals in the kernels kerberos handling. (bnc#1046107). - CVE-2017-7487: The ipxitf_ioctl function in net/ipx/af_ipx.c in the Linux kernel mishandled reference counts, which allowed local users to cause a denial of service (use-after-free) or possibly have unspecified other impact via a failed SIOCGIFADDR ioctl call for an IPX interface (bnc#1038879). - CVE-2017-7518: The Linux kernel was vulnerable to an incorrect debug exception(#DB) error. It could occur while emulating a syscall instruction and potentially lead to guest privilege escalation. (bsc#1045922). - CVE-2017-7541: The brcmf_cfg80211_mgmt_tx function in drivers/net/wireless/broadcom/brcm80211/brcmfmac/cfg8021 1.c in the Linux kernel allowed local users to cause a denial of service (buffer overflow and system crash) or possibly gain privileges via a crafted NL80211_CMD_FRAME Netlink packet (bnc#1049645). - CVE-2017-7542: The ip6_find_1stfragopt function in net/ipv6/output_core.c in the Linux kernel allowed local users to cause a denial of service (integer overflow and infinite loop) by leveraging the ability to open a raw socket (bnc#1049882). - CVE-2017-7889: The mm subsystem in the Linux kernel did not properly enforce the CONFIG_STRICT_DEVMEM protection mechanism, which allowed local users to read or write to kernel memory locations in the first megabyte (and bypass slab-allocation access restrictions) via an application that opens the /dev/mem file, related to arch/x86/mm/init.c and drivers/char/mem.c (bnc#1034405). - CVE-2017-8106: The handle_invept function in arch/x86/kvm/vmx.c in the Linux kernel 3.12 allowed privileged KVM guest OS users to cause a denial of service (NULL pointer dereference and host OS crash) via a single-context INVEPT instruction with a NULL EPT pointer (bnc#1035877). - CVE-2017-8831: The saa7164_bus_get function in drivers/media/pci/saa7164/saa7164-bus.c in the Linux kernel allowed local users to cause a denial of service (out-of-bounds array access) or possibly have unspecified other impact by changing a certain sequence-number value, aka a 'double fetch' vulnerability (bnc#1037994). - CVE-2017-8890: The inet_csk_clone_lock function in net/ipv4/inet_connection_sock.c in the Linux kernel allowed attackers to cause a denial of service (double free) or possibly have unspecified other impact by leveraging use of the accept system call (bnc#1038544). - CVE-2017-8924: The edge_bulk_in_callback function in drivers/usb/serial/io_ti.c in the Linux kernel allowed local users to obtain sensitive information (in the dmesg ringbuffer and syslog) from uninitialized kernel memory by using a crafted USB device (posing as an io_ti USB serial device) to trigger an integer underflow (bnc#1037182 bsc#1038982). - CVE-2017-8925: The omninet_open function in drivers/usb/serial/omninet.c in the Linux kernel allowed local users to cause a denial of service (tty exhaustion) by leveraging reference count mishandling (bnc#1037183 bsc#1038981). - CVE-2017-9074: The IPv6 fragmentation implementation in the Linux kernel did not consider that the nexthdr field may be associated with an invalid option, which allowed local users to cause a denial of service (out-of-bounds read and BUG) or possibly have unspecified other impact via crafted socket and send system calls (bnc#1039882). - CVE-2017-9075: The sctp_v6_create_accept_sk function in net/sctp/ipv6.c in the Linux kernel mishandled inheritance, which allowed local users to cause a denial of service or possibly have unspecified other impact via crafted system calls, a related issue to CVE-2017-8890 (bnc#1039883). - CVE-2017-9076: The dccp_v6_request_recv_sock function in net/dccp/ipv6.c in the Linux kernel mishandled inheritance, which allowed local users to cause a denial of service or possibly have unspecified other impact via crafted system calls, a related issue to CVE-2017-8890 (bnc#1039885). - CVE-2017-9077: The tcp_v6_syn_recv_sock function in net/ipv6/tcp_ipv6.c in the Linux kernel mishandled inheritance, which allowed local users to cause a denial of service or possibly have unspecified other impact via crafted system calls, a related issue to CVE-2017-8890 (bnc#1040069). - CVE-2017-9242: The __ip6_append_data function in net/ipv6/ip6_output.c in the Linux kernel is too late in checking whether an overwrite of an skb data structure may occur, which allowed local users to cause a denial of service (system crash) via crafted system calls (bnc#1041431).

    NASL id SUSE_SU-2017-2389-1.NASL
    description The SUSE Linux Enterprise 11 SP4 kernel was updated to receive various security and bugfixes. The following security bugs were fixed : - CVE-2017-7482: Several missing length checks ticket decode allowing for information leak or potentially code execution (bsc#1046107). - CVE-2016-10277: Potential privilege escalation due to a missing bounds check in the lp driver. A kernel command-line adversary can overflow the parport_nr array to execute code (bsc#1039456). - CVE-2017-7542: The ip6_find_1stfragopt function in net/ipv6/output_core.c in the Linux kernel allowed local users to cause a denial of service (integer overflow and infinite loop) by leveraging the ability to open a raw socket (bsc#1049882). - CVE-2017-7533: Bug in inotify code allowing privilege escalation (bsc#1049483). - CVE-2017-11176: The mq_notify function in the Linux kernel did not set the sock pointer to NULL upon entry into the retry logic. During a user-space close of a Netlink socket, it allowed attackers to cause a denial of service (use-after-free) or possibly have unspecified other impact (bsc#1048275). - CVE-2017-11473: Buffer overflow in the mp_override_legacy_irq() function in arch/x86/kernel/acpi/boot.c in the Linux kernel allowed local users to gain privileges via a crafted ACPI table (bnc#1049603). - CVE-2017-1000365: The Linux Kernel imposed a size restriction on the arguments and environmental strings passed through RLIMIT_STACK/RLIM_INFINITY (1/4 of the size), but did not take the argument and environment pointers into account, which allowed attackers to bypass this limitation. (bnc#1039354) - CVE-2014-9922: The eCryptfs subsystem in the Linux kernel allowed local users to gain privileges via a large filesystem stack that includes an overlayfs layer, related to fs/ecryptfs/main.c and fs/overlayfs/super.c (bnc#1032340) - CVE-2017-8924: The edge_bulk_in_callback function in drivers/usb/serial/io_ti.c in the Linux kernel allowed local users to obtain sensitive information (in the dmesg ringbuffer and syslog) from uninitialized kernel memory by using a crafted USB device (posing as an io_ti USB serial device) to trigger an integer underflow (bnc#1038982). - CVE-2017-8925: The omninet_open function in drivers/usb/serial/omninet.c in the Linux kernel allowed local users to cause a denial of service (tty exhaustion) by leveraging reference count mishandling (bnc#1038981). - CVE-2017-1000380: sound/core/timer.c was vulnerable to a data race in the ALSA /dev/snd/timer driver resulting in local users being able to read information belonging to other users, i.e., uninitialized memory contents could have bene disclosed when a read and an ioctl happen at the same time (bnc#1044125) - CVE-2017-9242: The __ip6_append_data function in net/ipv6/ip6_output.c was too late in checking whether an overwrite of an skb data structure may occur, which allowed local users to cause a denial of service (system crash) via crafted system calls (bnc#1041431) - CVE-2017-1000363: A buffer overflow in kernel commandline handling of the 'lp' parameter could be used by local console attackers to bypass certain secure boot settings. (bnc#1039456) - CVE-2017-9076: The dccp_v6_request_recv_sock function in net/dccp/ipv6.c in the Linux kernel mishandled inheritance, which allowed local users to cause a denial of service or possibly have unspecified other impact via crafted system calls, a related issue to CVE-2017-8890 (bnc#1039885) - CVE-2017-9077: The tcp_v6_syn_recv_sock function in net/ipv6/tcp_ipv6.c in the Linux kernel mishandled inheritance, which allowed local users to cause a denial of service or possibly have unspecified other impact via crafted system calls, a related issue to CVE-2017-8890 (bnc#1040069) - CVE-2017-9075: The sctp_v6_create_accept_sk function in net/sctp/ipv6.c in the Linux kernel mishandled inheritance, which allowed local users to cause a denial of service or possibly have unspecified other impact via crafted system calls, a related issue to CVE-2017-8890 (bnc#1039883) - CVE-2017-9074: The IPv6 fragmentation implementation in the Linux kernel did not consider that the nexthdr field may be associated with an invalid option, which allowed local users to cause a denial of service (out-of-bounds read and BUG) or possibly have unspecified other impact via crafted socket and send system calls (bnc#1039882) - CVE-2017-7487: The ipxitf_ioctl function in net/ipx/af_ipx.c in the Linux kernel mishandled reference counts, which allowed local users to cause a denial of service (use-after-free) or possibly have unspecified other impact via a failed SIOCGIFADDR ioctl call for an IPX interface (bnc#1038879) - CVE-2017-8890: The inet_csk_clone_lock function in net/ipv4/inet_connection_sock.c in the Linux kernel allowed attackers to cause a denial of service (double free) or possibly have unspecified other impact by leveraging use of the accept system call (bnc#1038544) - CVE-2017-2647: The KEYS subsystem in the Linux kernel allowed local users to gain privileges or cause a denial of service (NULL pointer dereference and system crash) via vectors involving a NULL value for a certain match field, related to the keyring_search_iterator function in keyring.c (bnc#1030593) - CVE-2017-6951: The keyring_search_aux function in security/keys/keyring.c in the Linux kernel allowed local users to cause a denial of service (NULL pointer dereference and OOPS) via a request_key system call for the 'dead' type (bnc#1029850) 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.
