    graphite2 vulnerabilities
    ==========================================================================
    
    A security issue affects these releases of Ubuntu and its derivatives:
    
    - Ubuntu 15.10
    - Ubuntu 14.04 LTS
    
    Summary:
    
    graphite2 could be made to crash or run programs as your login if it
    opened a specially crafted font.
    
    Software Description:
    - graphite2: Font rendering engine for Complex Scripts
    
    Details:
    
    Yves Younan discovered that graphite2 incorrectly handled certain malformed
    fonts. If a user or automated system were tricked into opening a specially-
    crafted font file, a remote attacker could use this issue to cause
    graphite2 to crash, resulting in a denial of service, or possibly execute
    arbitrary code.
    
    Update instructions:
    
    The problem can be corrected by updating your system to the following
    package versions:
    
    Ubuntu 15.10:
      libgraphite2-3                  1.2.4-3ubuntu1.1
    
    Ubuntu 14.04 LTS:
      libgraphite2-3                  1.2.4-1ubuntu1.1
    
    After a standard system update you need to restart applications using
    graphite2, such as LibreOffice, to make all the necessary changes.
