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.

    title SUSE SLES10 Security Update : kernel (SUSE-SU-2014:0536-1)
  • NASL family CentOS Local Security Checks
    NASL id CENTOS_RHSA-2013-1645.NASL
    description Updated kernel packages that fix multiple security issues, address several hundred bugs, and add numerous enhancements are now available as part of the ongoing support and maintenance of Red Hat Enterprise Linux version 6. This is the fifth regular update. The Red Hat Security Response Team has rated this update as having important security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section. The kernel packages contain the Linux kernel, the core of any Linux operating system. This update fixes the following security issues : * A flaw was found in the way the Linux kernel's IPv6 implementation handled certain UDP packets when the UDP Fragmentation Offload (UFO) feature was enabled. A remote attacker could use this flaw to crash the system or, potentially, escalate their privileges on the system. (CVE-2013-4387, Important) * A flaw was found in the way the Linux kernel handled the creation of temporary IPv6 addresses. If the IPv6 privacy extension was enabled (/proc/sys/net/ipv6/conf/eth0/use_tempaddr set to '2'), an attacker on the local network could disable IPv6 temporary address generation, leading to a potential information disclosure. (CVE-2013-0343, Moderate) * A flaw was found in the way the Linux kernel handled HID (Human Interface Device) reports with an out-of-bounds Report ID. An attacker with physical access to the system could use this flaw to crash the system or, potentially, escalate their privileges on the system. (CVE-2013-2888, Moderate) * An off-by-one flaw was found in the way the ANSI CPRNG implementation in the Linux kernel processed non-block size aligned requests. This could lead to random numbers being generated with less bits of entropy than expected when ANSI CPRNG was used. (CVE-2013-4345, Moderate) * It was found that the fix for CVE-2012-2375 released via RHSA-2012:1580 accidentally removed a check for small-sized result buffers. A local, unprivileged user with access to an NFSv4 mount with ACL support could use this flaw to crash the system or, potentially, escalate their privileges on the system . (CVE-2013-4591, Moderate) * A flaw was found in the way IOMMU memory mappings were handled when moving memory slots. A malicious user on a KVM host who has the ability to assign a device to a guest could use this flaw to crash the host. (CVE-2013-4592, Moderate) * Heap-based buffer overflow flaws were found in the way the Zeroplus and Pantherlord/GreenAsia game controllers handled HID reports. An attacker with physical access to the system could use these flaws to crash the system or, potentially, escalate their privileges on the system. (CVE-2013-2889, CVE-2013-2892, Moderate) * Two information leak flaws were found in the logical link control (LLC) implementation in the Linux kernel. A local, unprivileged user could use these flaws to leak kernel stack memory to user space. (CVE-2012-6542, CVE-2013-3231, Low) * A heap-based buffer overflow in the way the tg3 Ethernet driver parsed the vital product data (VPD) of devices could allow an attacker with physical access to a system to cause a denial of service or, potentially, escalate their privileges. (CVE-2013-1929, Low) * Information leak flaws in the Linux kernel could allow a privileged, local user to leak kernel memory to user space. (CVE-2012-6545, CVE-2013-1928, CVE-2013-2164, CVE-2013-2234, Low) * A format string flaw was found in the Linux kernel's block layer. A privileged, local user could potentially use this flaw to escalate their privileges to kernel level (ring0). (CVE-2013-2851, Low) Red Hat would like to thank Stephan Mueller for reporting CVE-2013-4345, and Kees Cook for reporting CVE-2013-2851. This update also fixes several hundred bugs and adds enhancements. Refer to the Red Hat Enterprise Linux 6.5 Release Notes for information on the most significant of these changes, and the Technical Notes for further information, both linked to in the References. All Red Hat Enterprise Linux 6 users are advised to install these updated packages, which correct these issues, and fix the bugs and add the enhancements noted in the Red Hat Enterprise Linux 6.5 Release Notes and Technical Notes. The system must be rebooted for this update to take effect.

    description From Red Hat Security Advisory 2013:0747 : Updated kernel packages that fix several security issues and three bugs are now available for Red Hat Enterprise Linux 5. The Red Hat Security Response Team has rated this update as having moderate security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section. The kernel packages contain the Linux kernel, the core of any Linux operating system. This update fixes the following security issues : * A flaw was found in the Xen netback driver implementation in the Linux kernel. A privileged guest user with access to a para-virtualized network device could use this flaw to cause a long loop in netback, leading to a denial of service that could potentially affect the entire system. (CVE-2013-0216, Moderate) * A flaw was found in the Xen PCI device back-end driver implementation in the Linux kernel. A privileged guest user in a guest that has a PCI passthrough device could use this flaw to cause a denial of service that could potentially affect the entire system. (CVE-2013-0231, Moderate) * A NULL pointer dereference flaw was found in the IP packet transformation framework (XFRM) implementation in the Linux kernel. A local user who has the CAP_NET_ADMIN capability could use this flaw to cause a denial of service. (CVE-2013-1826, Moderate) * Information leak flaws were found in the XFRM implementation in the Linux kernel. A local user who has the CAP_NET_ADMIN capability could use these flaws to leak kernel stack memory to user-space. (CVE-2012-6537, Low) * An information leak flaw was found in the logical link control (LLC) implementation in the Linux kernel. A local, unprivileged user could use this flaw to leak kernel stack memory to user-space. (CVE-2012-6542, Low) * Two information leak flaws were found in the Linux kernel's Asynchronous Transfer Mode (ATM) subsystem. A local, unprivileged user could use these flaws to leak kernel stack memory to user-space. (CVE-2012-6546, Low) * An information leak flaw was found in the TUN/TAP device driver in the Linux kernel's networking implementation. A local user with access to a TUN/TAP virtual interface could use this flaw to leak kernel stack memory to user-space. (CVE-2012-6547, Low) Red Hat would like to thank the Xen project for reporting the CVE-2013-0216 and CVE-2013-0231 issues. This update also fixes the following bugs : * The IPv4 code did not correctly update the Maximum Transfer Unit (MTU) of the designed interface when receiving ICMP Fragmentation Needed packets. Consequently, a remote host did not respond correctly to ping attempts. With this update, the IPv4 code has been modified so the MTU of the designed interface is adjusted as expected in this situation. The ping command now provides the expected output. (BZ#923353) * Previously, the be2net code expected the last word of an MCC completion message from the firmware to be transferred by direct memory access (DMA) at once. However, this is not always true, and could therefore cause the BUG_ON() macro to be triggered in the be_mcc_compl_is_new() function, consequently leading to a kernel panic. The BUG_ON() macro has been removed from be_mcc_compl_is_new(), and the kernel panic no longer occurs in this scenario. (BZ#923910) * Previously, the NFSv3 server incorrectly converted 64-bit cookies to 32-bit. Consequently, the cookies became invalid, which affected all file system operations depending on these cookies, such as the READDIR operation that is used to read entries from a directory. This led to various problems, such as exported directories being empty or displayed incorrectly, or an endless loop of the READDIRPLUS procedure which could potentially cause a buffer overflow. This update modifies knfsd code so that 64-bit cookies are now handled correctly and all file system operations work as expected. (BZ#924087) Users should upgrade to these updated packages, which contain backported patches to correct these issues. The system must be rebooted for this update to take effect.

    description From Red Hat Security Advisory 2013:1645 : Updated kernel packages that fix multiple security issues, address several hundred bugs, and add numerous enhancements are now available as part of the ongoing support and maintenance of Red Hat Enterprise Linux version 6. This is the fifth regular update. The Red Hat Security Response Team has rated this update as having important security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section. The kernel packages contain the Linux kernel, the core of any Linux operating system. This update fixes the following security issues : * A flaw was found in the way the Linux kernel's IPv6 implementation handled certain UDP packets when the UDP Fragmentation Offload (UFO) feature was enabled. A remote attacker could use this flaw to crash the system or, potentially, escalate their privileges on the system. (CVE-2013-4387, Important) * A flaw was found in the way the Linux kernel handled the creation of temporary IPv6 addresses. If the IPv6 privacy extension was enabled (/proc/sys/net/ipv6/conf/eth0/use_tempaddr set to '2'), an attacker on the local network could disable IPv6 temporary address generation, leading to a potential information disclosure. (CVE-2013-0343, Moderate) * A flaw was found in the way the Linux kernel handled HID (Human Interface Device) reports with an out-of-bounds Report ID. An attacker with physical access to the system could use this flaw to crash the system or, potentially, escalate their privileges on the system. (CVE-2013-2888, Moderate) * An off-by-one flaw was found in the way the ANSI CPRNG implementation in the Linux kernel processed non-block size aligned requests. This could lead to random numbers being generated with less bits of entropy than expected when ANSI CPRNG was used. (CVE-2013-4345, Moderate) * It was found that the fix for CVE-2012-2375 released via RHSA-2012:1580 accidentally removed a check for small-sized result buffers. A local, unprivileged user with access to an NFSv4 mount with ACL support could use this flaw to crash the system or, potentially, escalate their privileges on the system . (CVE-2013-4591, Moderate) * A flaw was found in the way IOMMU memory mappings were handled when moving memory slots. A malicious user on a KVM host who has the ability to assign a device to a guest could use this flaw to crash the host. (CVE-2013-4592, Moderate) * Heap-based buffer overflow flaws were found in the way the Zeroplus and Pantherlord/GreenAsia game controllers handled HID reports. An attacker with physical access to the system could use these flaws to crash the system or, potentially, escalate their privileges on the system. (CVE-2013-2889, CVE-2013-2892, Moderate) * Two information leak flaws were found in the logical link control (LLC) implementation in the Linux kernel. A local, unprivileged user could use these flaws to leak kernel stack memory to user space. (CVE-2012-6542, CVE-2013-3231, Low) * A heap-based buffer overflow in the way the tg3 Ethernet driver parsed the vital product data (VPD) of devices could allow an attacker with physical access to a system to cause a denial of service or, potentially, escalate their privileges. (CVE-2013-1929, Low) * Information leak flaws in the Linux kernel could allow a privileged, local user to leak kernel memory to user space. (CVE-2012-6545, CVE-2013-1928, CVE-2013-2164, CVE-2013-2234, Low) * A format string flaw was found in the Linux kernel's block layer. A privileged, local user could potentially use this flaw to escalate their privileges to kernel level (ring0).

A local user could exploit this flaw to examine some of the kernel's stack memory. (CVE-2012-6542) Mathias Krause discovered information leaks in the Linux kernel's Bluetooth Logical Link Control and Adaptation Protocol (L2CAP) implementation. A local user could exploit these flaws to examine some of the kernel's stack memory. (CVE-2012-6544) Mathias Krause discovered information leaks in the Linux kernel's Bluetooth RFCOMM protocol implementation. A local user could exploit these flaws to examine parts of kernel memory. (CVE-2012-6545) Mathias Krause discovered information leaks in the Linux kernel's Asynchronous Transfer Mode (ATM) networking stack. A local user could exploit these flaws to examine some parts of kernel memory. (CVE-2012-6546) Mathias Krause discovered an information leak in the Linux kernel's UDF file system implementation. A local user could exploit this flaw to examine some of the kernel's heap memory. (CVE-2012-6548) Andrew Jones discovered a flaw with the xen_iret function in Linux kernel's Xen virtualizeation. In the 32-bit Xen paravirt platform an unprivileged guest OS user could exploit this flaw to cause a denial of service (crash the system) or gain guest OS privilege. (CVE-2013-0228) An information leak was discovered in the Linux kernel's Bluetooth stack when HIDP (Human Interface Device Protocol) support is enabled. A local unprivileged user could exploit this flaw to cause an information leak from the kernel. (CVE-2013-0349) A flaw was discovered in the Edgeort USB serial converter driver when the device is disconnected while it is in use. A local user could exploit this flaw to cause a denial of service (system crash). (CVE-2013-1774) Andrew Honig discovered a flaw in guest OS time updates in the Linux kernel's KVM (Kernel-based Virtual Machine). A privileged guest user could exploit this flaw to cause a denial of service (crash host system) or potential escalate privilege to the host kernel level. (CVE-2013-1796). Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

    NASL id CENTOS_RHSA-2013-0747.NASL
    description Updated kernel packages that fix several security issues and three bugs are now available for Red Hat Enterprise Linux 5. The Red Hat Security Response Team has rated this update as having moderate security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section. The kernel packages contain the Linux kernel, the core of any Linux operating system. This update fixes the following security issues : * A flaw was found in the Xen netback driver implementation in the Linux kernel. A privileged guest user with access to a para-virtualized network device could use this flaw to cause a long loop in netback, leading to a denial of service that could potentially affect the entire system. (CVE-2013-0216, Moderate) * A flaw was found in the Xen PCI device back-end driver implementation in the Linux kernel. A privileged guest user in a guest that has a PCI passthrough device could use this flaw to cause a denial of service that could potentially affect the entire system. (CVE-2013-0231, Moderate) * A NULL pointer dereference flaw was found in the IP packet transformation framework (XFRM) implementation in the Linux kernel. A local user who has the CAP_NET_ADMIN capability could use this flaw to cause a denial of service. (CVE-2013-1826, Moderate) * Information leak flaws were found in the XFRM implementation in the Linux kernel. A local user who has the CAP_NET_ADMIN capability could use these flaws to leak kernel stack memory to user-space. (CVE-2012-6537, Low) * An information leak flaw was found in the logical link control (LLC) implementation in the Linux kernel. A local, unprivileged user could use this flaw to leak kernel stack memory to user-space. (CVE-2012-6542, Low) * Two information leak flaws were found in the Linux kernel's Asynchronous Transfer Mode (ATM) subsystem. A local, unprivileged user could use these flaws to leak kernel stack memory to user-space. (CVE-2012-6546, Low) * An information leak flaw was found in the TUN/TAP device driver in the Linux kernel's networking implementation. A local user with access to a TUN/TAP virtual interface could use this flaw to leak kernel stack memory to user-space. (CVE-2012-6547, Low) Red Hat would like to thank the Xen project for reporting the CVE-2013-0216 and CVE-2013-0231 issues. This update also fixes the following bugs : * The IPv4 code did not correctly update the Maximum Transfer Unit (MTU) of the designed interface when receiving ICMP Fragmentation Needed packets. Consequently, a remote host did not respond correctly to ping attempts. With this update, the IPv4 code has been modified so the MTU of the designed interface is adjusted as expected in this situation. The ping command now provides the expected output. (BZ#923353) * Previously, the be2net code expected the last word of an MCC completion message from the firmware to be transferred by direct memory access (DMA) at once. However, this is not always true, and could therefore cause the BUG_ON() macro to be triggered in the be_mcc_compl_is_new() function, consequently leading to a kernel panic. The BUG_ON() macro has been removed from be_mcc_compl_is_new(), and the kernel panic no longer occurs in this scenario. (BZ#923910) * Previously, the NFSv3 server incorrectly converted 64-bit cookies to 32-bit. Consequently, the cookies became invalid, which affected all file system operations depending on these cookies, such as the READDIR operation that is used to read entries from a directory. This led to various problems, such as exported directories being empty or displayed incorrectly, or an endless loop of the READDIRPLUS procedure which could potentially cause a buffer overflow. This update modifies knfsd code so that 64-bit cookies are now handled correctly and all file system operations work as expected. (BZ#924087) Users should upgrade to these updated packages, which contain backported patches to correct these issues. The system must be rebooted for this update to take effect.
