    ghostscript vulnerability
    ==========================================================================
    
    A security issue affects these releases of Ubuntu and its derivatives:
    
    - Ubuntu 19.10
    - Ubuntu 19.04
    - Ubuntu 18.04 LTS
    - Ubuntu 16.04 LTS
    
    Summary:
    
    Ghostscript could be made to crash, access files, or run programs if it
    opened a specially crafted file.
    
    Software Description:
    - ghostscript: PostScript and PDF interpreter
    
    Details:
    
    Paul Manfred and Lukas Schauer discovered that Ghostscript incorrectly
    handled certain PostScript files. If a user or automated system were
    tricked into processing a specially crafted file, a remote attacker could
    possibly use this issue to access arbitrary files, execute arbitrary code,
    or cause a denial of service.
    
    Update instructions:
    
    The problem can be corrected by updating your system to the following
    package versions:
