The SUSE Linux Enterprise 11 SP2 kernel was updated to 3.0.31, fixing many bugs and security issues.

Various security and bug fixes contained in the Linux 3.0 stable releases 3.0.27 up to 3.0.31 have been included, but are not explicitly listed below.

The following notable security issues have been fixed :

  - The dl2k network card driver lacked permission handling     for some ethtool ioctls, which could allow local     attackers to start/stop the network card.
    (CVE-2012-2313)

  - A use after free bug in hugetlb support could be used by     local attackers to crash the system. (CVE-2012-2133)

  - Various leaks in namespace handling over fork where     fixed, which could be exploited by e.g. vsftpd access by     remote users. (CVE-2012-2127)

  - A memory corruption when mounting a hfsplus filesystem     was fixed that could be used by local attackers able to     mount filesystem to crash the system. (CVE-2012-2319)

Vadim Ponomarev discovered a flaw in the Linux kernel causing a reference leak when PID namespaces are used. A remote attacker could exploit this flaw causing a denial of service. (CVE-2012-2127)

A flaw was found in how the Linux kernel's KVM (Kernel-based Virtual Machine) subsystem handled MSI (Message Signaled Interrupts). A local unprivileged user could exploit this flaw to cause a denial of service or potentially elevate privileges. (CVE-2012-2137).

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.
