    libav vulnerabilities
    ==========================================================================
    
    A security issue affects these releases of Ubuntu and its derivatives:
    
    - Ubuntu 12.04 LTS
    
    Summary:
    
    Libav could be made to crash or run programs as your login if it opened a
    specially crafted file.
    
    Software Description:
    - libav: Multimedia player, server, encoder and transcoder
    
    Details:
    
    It was discovered that Libav incorrectly handled certain malformed media
    files. If a user were tricked into opening a crafted media file, an
    attacker could cause a denial of service via application crash, or possibly
    execute arbitrary code with the privileges of the user invoking the
    program.
    
    Update instructions:
    
    The problem can be corrected by updating your system to the following
    package versions:
    
    Ubuntu 12.04 LTS:
      libavcodec53                    4:0.8.17-0ubuntu0.12.04.2
      libavformat53                   4:0.8.17-0ubuntu0.12.04.2
    
    In general, a standard system update will make all the necessary changes.
