    Ubuntu Security Notice USN-1949-1
    September 10, 2013
    
    imagemagick vulnerability
    ==========================================================================
    
    A security issue affects these releases of Ubuntu and its derivatives:
    
    - Ubuntu 13.04
    - Ubuntu 12.10
    
    Summary:
    
    ImageMagick could be made to crash or run programs as your login if it
    opened a specially crafted file.
    
    Software Description:
    - imagemagick: Image manipulation programs and library
    
    Details:
    
    It was discovered that ImageMagick incorrectly handled decoding GIF image
    comments. If a user or automated system using ImageMagick were tricked into
    opening a specially crafted GIF image, an attacker could exploit this to
    cause a denial of service or possibly execute 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 13.04:
      libmagick++5                    8:6.7.7.10-5ubuntu2.1
      libmagickcore5                  8:6.7.7.10-5ubuntu2.1
    
    Ubuntu 12.10:
      libmagick++5                    8:6.7.7.10-2ubuntu4.1
      libmagickcore5                  8:6.7.7.10-2ubuntu4.1
    
    In general, a standard system update will make all the necessary changes.
