    <p>Multiple vulnerabilities have been discovered in GPL Ghostscript and the
      bundled OpenJPEG. Please review the CVE identifiers and GLSA-201612-26
      (OpenJPEG) referenced below for additional information.
    </p>
    
    <p>Note: GPL Ghostscript in Gentoo since app-text/ghostscript-gpl-9.20-r1
      no longer bundles OpenJPEG.

  <impact type="normal">
    <p>A context-dependent attacker could entice a user to open a specially
      crafted PostScript file or PDF using GPL Ghostscript possibly resulting
      in the execution of arbitrary code with the privileges of the process or
      a Denial of Service condition.
    </p>
  </impact>
  <workaround>
    <p>There is no known workaround at this time.</p>
  </workaround>
  <resolution>
    <p>All GPL Ghostscript users should upgrade to the latest version:</p>
    
    <code>
      # emerge --sync
      # emerge --ask --oneshot --verbose
      "&gt;=app-text/ghostscript-gpl-9.20-r1"
    </code>
