    Portable Document Format (PDF).

    <p>
    Jan Lieskovsky from the Red Hat Security Response Team discovered the
    following vulnerabilities in Ghostscript's ICC Library:
    </p>
    <ul>
    <li>Multiple integer overflows (CVE-2009-0583).</li>
    <li>Multiple
    insufficient bounds checks on certain variable sizes
    (CVE-2009-0584).</li>
    </ul>
  </description>
  <impact type="normal">
    <p>
    A remote attacker could entice a user to open a specially crafted
    PostScript file containing images and a malicious ICC profile, possibly
    resulting in the execution of arbitrary code with the privileges of the
    user running the application.
    </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 &quot;&gt;=app-text/ghostscript-gpl-8.64-r2&quot;</code>
    <p>
    All GNU Ghostscript users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose &quot;&gt;=app-text/ghostscript-gnu-8.62.0&quot;</code>
    <p>
    We recommend that users unmerge ESP Ghostscript and use GPL or GNU
    Ghostscript instead:
    </p>
    <code>
    # emerge --unmerge &quot;app-text/ghostscript-esp&quot;</code>
    <p>
    For installation instructions, see above.
