    ==========================================================================
    
    A security issue affects these releases of Ubuntu and its derivatives:
    
    - Ubuntu 18.04 LTS
    - Ubuntu 16.04 LTS
    - Ubuntu 14.04 LTS
    
    Summary:
    
    Several security issues were fixed in Ghostscript.
    
    Software Description:
    - ghostscript: PostScript and PDF interpreter
    
    Details:
    
    Tavis Ormandy discovered multiple security issues in Ghostscript. If a user
    or automated system were tricked into processing a specially crafted file,
    a remote attacker could possibly use these issues 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:
    
    Ubuntu 18.04 LTS:
      ghostscript                     9.22~dfsg+1-0ubuntu1.2
      libgs9                          9.22~dfsg+1-0ubuntu1.2
    
    Ubuntu 16.04 LTS:
      ghostscript                     9.18~dfsg~0-0ubuntu2.9
      libgs9                          9.18~dfsg~0-0ubuntu2.9
    
    Ubuntu 14.04 LTS:
      ghostscript                     9.10~dfsg-0ubuntu10.13
      libgs9                          9.10~dfsg-0ubuntu10.13
    
    In general, a standard system update will make all the necessary changes.
