    Ubuntu Security Notice USN-2134-1

    linux-ti-omap4 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-ti-omap4: Linux kernel for OMAP4
    Mathy Vanhoef discovered an error in the the way the ath9k driver was
    handling the BSSID masking. A remote attacker could exploit this error to
    discover the original MAC address after a spoofing atack. (CVE-2013-4579)
    Andrew Honig reported an error in the Linux Kernel's Kernel Virtual Machine
    (KVM) VAPIC synchronization operation. A local user could exploit this flaw
    to gain privileges or cause a denial of service (system crash).
    halfdog reported an error in the AMD K7 and K8 platform support in the
    Linux kernel. An unprivileged local user could exploit this flaw on AMD
    based systems to cause a denial of service (task kill) or possibly gain
    privileges via a crafted application. (CVE-2014-1438)
    An information leak was discovered in the Linux kernel's hamradio YAM
    driver for AX.25 packet radio. A local user with the CAP_NET_ADMIN
    capability could exploit this flaw to obtain sensitive information from
    kernel memory. (CVE-2014-1446)
    Matthew Thode reported a denial of service vulnerability in the Linux
    kernel when SELinux support is enabled. A local user with the CAP_MAC_ADMIN
    capability (and the SELinux mac_admin permission if running in enforcing
    mode) could exploit this flaw to cause a denial of service (kernel crash).
    Update instructions:
    The problem can be corrected by updating your system to the following
    package versions:
    Ubuntu 12.04 LTS:
      linux-image-3.2.0-1444-omap4    3.2.0-1444.63
    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-2013-4579, CVE-2013-6368, CVE-2014-1438, CVE-2014-1446,
