    Ubuntu Security Notice USN-3144-1
    November 30, 2016
    
    linux vulnerability
    ==========================================================================
    
    A security issue affects these releases of Ubuntu and its derivatives:
    
    - Ubuntu 12.04 LTS
    
    Summary:
    
    The system could be made to crash under certain conditions.
    
    Software Description:
    - linux: Linux kernel
    
    Details:
    
    Marco Grassi discovered that the driver for Areca RAID Controllers in the
    Linux kernel did not properly validate control messages. A local attacker
    could use this to cause a denial of service (system crash) or possibly gain
    privileges.
    
    Update instructions:
    
    The problem can be corrected by updating your system to the following
    package versions:
    
    Ubuntu 12.04 LTS:
      linux-image-3.2.0-116-generic   3.2.0-116.158
      linux-image-3.2.0-116-generic-pae  3.2.0-116.158
      linux-image-3.2.0-116-highbank  3.2.0-116.158
      linux-image-3.2.0-116-omap      3.2.0-116.158
      linux-image-3.2.0-116-powerpc-smp  3.2.0-116.158
      linux-image-3.2.0-116-powerpc64-smp  3.2.0-116.158
      linux-image-3.2.0-116-virtual   3.2.0-116.158
      linux-image-generic             3.2.0.116.132
      linux-image-generic-pae         3.2.0.116.132
      linux-image-highbank            3.2.0.116.132
      linux-image-omap                3.2.0.116.132
      linux-image-powerpc-smp         3.2.0.116.132
      linux-image-powerpc64-smp       3.2.0.116.132
      linux-image-virtual             3.2.0.116.132
    
    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.
    Unless you manually uninstalled the standard kernel metapackages
    (e.g. linux-generic, linux-generic-lts-RELEASE, linux-virtual,
    linux-powerpc), a standard system upgrade will automatically perform
    this as well.
