    linux-ti-omap4 vulnerabilities
    ==========================================================================
    
    A security issue affects these releases of Ubuntu and its derivatives:
    
    - Ubuntu 12.04 LTS
    
    Summary:
    
    Several security issues were fixed in the kernel.
    
    Software Description:
    - linux-ti-omap4: Linux kernel for OMAP4
    
    Details:
    
    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).
    (CVE-2013-6368)
    
    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).
    (CVE-2014-1874)
    
    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.
