    tiff vulnerabilities
    ==========================================================================
    
    A security issue affects these releases of Ubuntu and its derivatives:
    
    - Ubuntu 18.10
    - Ubuntu 18.04 LTS
    - Ubuntu 16.04 LTS
    - Ubuntu 14.04 LTS
    
    Summary:
    
    LibTIFF could be made to crash or run programs as your login if it opened a
    specially crafted file.
    
    Software Description:
    - tiff: Tag Image File Format (TIFF) library
    
    Details:
    
    It was discovered that LibTIFF incorrectly handled certain malformed
    images. If a user or automated system were tricked into opening a specially
    crafted image, a remote attacker could crash the application, leading to a
    denial of service, or possibly execute arbitrary code with user privileges.
    
    Update instructions:
    
    The problem can be corrected by updating your system to the following
    package versions:
    
    Ubuntu 18.10:
      libtiff-tools                   4.0.9-6ubuntu0.1
      libtiff5                        4.0.9-6ubuntu0.1
    
    Ubuntu 18.04 LTS:
      libtiff-tools                   4.0.9-5ubuntu0.1
      libtiff5                        4.0.9-5ubuntu0.1
    
    Ubuntu 16.04 LTS:
      libtiff-tools                   4.0.6-1ubuntu0.5
      libtiff5                        4.0.6-1ubuntu0.5
    
    Ubuntu 14.04 LTS:
      libtiff-tools                   4.0.3-7ubuntu0.10
      libtiff5                        4.0.3-7ubuntu0.10
    
    In general, a standard system update will make all the necessary changes.
