    ghostscript vulnerabilities
    ==========================================================================
    
    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:
    
    It was discovered that Ghostscript contained multiple security issues. 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                     9.25~dfsg+1-0ubuntu0.18.04.1
      libgs9                          9.25~dfsg+1-0ubuntu0.18.04.1
    
    Ubuntu 16.04 LTS:
      ghostscript                     9.25~dfsg+1-0ubuntu0.16.04.1
      libgs9                          9.25~dfsg+1-0ubuntu0.16.04.1
    
    Ubuntu 14.04 LTS:
      ghostscript                     9.25~dfsg+1-0ubuntu0.14.04.1
      libgs9                          9.25~dfsg+1-0ubuntu0.14.04.1
    
    This update uses a new upstream release, which includes additional bug
    fixes. In general, a standard system update will make all the necessary
    changes.
