    libreoffice vulnerabilities
    ==========================================================================
    
    A security issue affects these releases of Ubuntu and its derivatives:
    
    - Ubuntu 16.10
    - Ubuntu 16.04 LTS
    - Ubuntu 14.04 LTS
    
    Summary:
    
    LibreOffice could be made to crash or run programs as your login if it
    opened a specially crafted EMF file.
    
    Software Description:
    - libreoffice: Office productivity suite
    
    Details:
    
    It was discovered that LibreOffice incorrectly handled EMF image files.
    If a user were tricked into opening a specially crafted EMF image file, a
    remote attacker could cause LibreOffice to crash, and possibly execute
    arbitrary code.
    
    Update instructions:
    
    The problem can be corrected by updating your system to the following
    package versions:
    
    Ubuntu 16.10:
      libreoffice-core                1:5.2.2-0ubuntu2.1
    
    Ubuntu 16.04 LTS:
      libreoffice-core                1:5.1.6~rc2-0ubuntu1~xenial2
    
    Ubuntu 14.04 LTS:
      libreoffice-core                1:4.2.8-0ubuntu5.1
    
    After a standard system update you need to restart LibreOffice to make all
    the necessary changes.
