    linux vulnerabilities
    A security issue affects these releases of Ubuntu and its derivatives:
    - Ubuntu 12.04 LTS
    Several security issues were fixed in the kernel.
    Software Description:
    - linux: Linux kernel
    Andy Lutomirski discover an error in the Linux kernel's credential handling
    on unix sockets. A local user could exploit this flaw to gain
    administrative privileges. (CVE-2013-1979)
    A buffer overflow vulnerability was discovered in the Broadcom tg3 ethernet
    driver for the Linux kernel. A local user could exploit this flaw to cause
    a denial of service (crash the system) or potentially escalate privileges
    on the system. (CVE-2013-1929)
    A flaw was discovered in the Linux kernel's ftrace subsystem interface. A
    local user could exploit this flaw to cause a denial of service (system
    crash). (CVE-2013-3301)
    Update instructions:
    The problem can be corrected by updating your system to the following
    package versions:
    Ubuntu 12.04 LTS:
      linux-image-3.2.0-44-generic    3.2.0-44.69
      linux-image-3.2.0-44-generic-pae  3.2.0-44.69
      linux-image-3.2.0-44-highbank   3.2.0-44.69
      linux-image-3.2.0-44-omap       3.2.0-44.69
      linux-image-3.2.0-44-powerpc-smp  3.2.0-44.69
      linux-image-3.2.0-44-powerpc64-smp  3.2.0-44.69
      linux-image-3.2.0-44-virtual    3.2.0-44.69
    After a standard system update you need to reboot your computer to make
    all the necessary changes.
    ATTENTION: Due to an unavoidable ABI change the kernel updates have
    been given a new version number, which requires you to recompile and
    reinstall all third party kernel modules you might have installed. If
    you use linux-restricted-modules, you have to update that package as
    well to get modules which work with the new kernel version. Unless you
    manually uninstalled the standard kernel metapackages (e.g. linux-generic,
    linux-server, linux-powerpc), a standard system upgrade will automatically
    perform this as well.
      CVE-2013-1929, CVE-2013-1979, CVE-2013-3301
