  <background>
    <p>
    lighttpd is a lightweight high-performance web server.
    </p>
  </background>
  <description>
    <p>
    Multiple vulnerabilities have been reported in lighttpd:
    </p>
    <ul>
    <li>
    Qhy reported a memory leak in the http_request_parse() function in
    request.c (CVE-2008-4298).
    </li>
    <li>
    Gaetan Bisson reported that URIs are not decoded before applying
    url.redirect and url.rewrite rules (CVE-2008-4359).
    </li>
    <li>
    Anders1 reported that mod_userdir performs case-sensitive comparisons
    on filename components in configuration options, which is insufficient
    when case-insensitive filesystems are used (CVE-2008-4360).
    </li>
    </ul>
  </description>
  <impact type="normal">
    <p>
    A remote attacker could exploit these vulnerabilities to cause a Denial
    of Service, to bypass intended access restrictions, to obtain sensitive
    information, or to possibly modify data.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All lighttpd users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose "&gt;=www-servers/lighttpd-1.4.20"</code>
  </resolution>
