    gpac vulnerabilities
    ==========================================================================
    
    A security issue affects these releases of Ubuntu and its derivatives:
    
    - Ubuntu 18.10
    - Ubuntu 18.04 LTS
    - Ubuntu 16.04 LTS
    
    Summary:
    
    GPAC could be made to crash or run programs as your login if it
    opened a specially crafted file.
    
    Software Description:
    - gpac: GPAC Project on Advanced Content
    
    Details:
    
    It was discovered that the GPAC MP4Box utility incorrectly handled certain
    memory operations. If an user or automated system were tricked into opening a
    specially crafted MP4 file, a remote attacker could use this issue to cause
    MP4Box 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 18.10:
      gpac                            0.5.2-426-gc5ad4e4+dfsg5-4ubuntu0.1
      gpac-modules-base               0.5.2-426-gc5ad4e4+dfsg5-4ubuntu0.1
      libgpac4                        0.5.2-426-gc5ad4e4+dfsg5-4ubuntu0.1
    
    Ubuntu 18.04 LTS:
      gpac                            0.5.2-426-gc5ad4e4+dfsg5-3ubuntu0.1
      gpac-modules-base               0.5.2-426-gc5ad4e4+dfsg5-3ubuntu0.1
      libgpac4                        0.5.2-426-gc5ad4e4+dfsg5-3ubuntu0.1
    
    Ubuntu 16.04 LTS:
      gpac                            0.5.2-426-gc5ad4e4+dfsg5-1ubuntu0.1
      gpac-modules-base               0.5.2-426-gc5ad4e4+dfsg5-1ubuntu0.1
      libgpac4                        0.5.2-426-gc5ad4e4+dfsg5-1ubuntu0.1
