    Ubuntu Security Notice USN-3106-1
    October 20, 2016
    
    linux vulnerability
    ==========================================================================
    
    A security issue affects these releases of Ubuntu and its derivatives:
    
    - Ubuntu 16.04 LTS
    
    Summary:
    
    The system could be made to run programs as an administrator.
    
    Software Description:
    - linux: Linux kernel
    
    Details:
    
    It was discovered that a race condition existed in the memory manager of
    the Linux kernel when handling copy-on-write breakage of private read-only
    memory mappings. A local attacker could use this to gain administrative
    privileges.
    
    Update instructions:
    
    The problem can be corrected by updating your system to the following
    package versions:
    
    Ubuntu 16.04 LTS:
      linux-image-4.4.0-45-generic    4.4.0-45.66
      linux-image-4.4.0-45-generic-lpae  4.4.0-45.66
      linux-image-4.4.0-45-lowlatency  4.4.0-45.66
      linux-image-4.4.0-45-powerpc-e500mc  4.4.0-45.66
      linux-image-4.4.0-45-powerpc-smp  4.4.0-45.66
      linux-image-4.4.0-45-powerpc64-emb  4.4.0-45.66
      linux-image-4.4.0-45-powerpc64-smp  4.4.0-45.66
    
    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.
