  <impact type="normal">
    <p>
    A remote attacker could entice a user to open an HTML document
    containing a specially crafted, large PNG image, 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 Dillo users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose "&gt;=www-client/dillo-2.1.1"</code>
