    <p>
    The following vulnerabilities were found and fixed in Mozilla
    Firefox:
    </p>
    <ul>
    <li>Mark Dowd from ISS X-Force reported an
    exploitable heap overrun in the GIF processing of obsolete Netscape
    extension 2 (CAN-2005-0399)</li>
    <li>Kohei Yoshino discovered that a
    page bookmarked as a sidebar could bypass privileges control
    (CAN-2005-0402)</li>
    <li>Michael Krax reported a new way to bypass XUL
    security restrictions through drag-and-drop of items like scrollbars
    (CAN-2005-0401)</li>
    </ul>
  </description>
  <impact type="normal">
    <ul>
    <li>The GIF heap overflow could be triggered by a malicious GIF
    image that would end up executing arbitrary code with the rights of the
    user running Firefox</li>
    <li>By tricking the user into bookmarking a
    malicious page as a Sidebar, a remote attacker could potentially
    execute arbitrary code with the rights of the user running the
    browser</li>
    <li>By setting up a malicious website and convincing users
    to obey very specific drag-and-drop instructions, attackers may
    leverage drag-and-drop features to bypass XUL security restrictions,
    which could be used as a stepping stone to exploit other
    vulnerabilities</li>
    </ul>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All Mozilla Firefox users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose "&gt;=www-client/mozilla-firefox-1.0.2"</code>
    <p>
    All Mozilla Firefox binary users should upgrade to the latest
    version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose "&gt;=www-client/mozilla-firefox-bin-1.0.2"</code>
  </resolution>
