  <title>Lighttpd: Multiple vulnerabilities</title>
  <synopsis>
    Several vulnerabilities were reported in Lighttpd, most of them allowing a
    Denial of Service and potentially the remote execution of arbitrary code.

    <p>
    Lighttpd is a lightweight HTTP web server.

  <description>
    <p>
    Stefan Esser discovered errors with evidence of memory corruption in
    the code parsing the headers. Several independent researchers also
    reported errors involving the handling of HTTP headers, the mod_auth
    and mod_scgi modules, and the limitation of active connections.
    </p>
  </description>
  <impact type="normal">
    <p>
    A remote attacker can trigger any of these vulnerabilities by sending
    malicious data to the server, which may lead to a crash or memory
    exhaustion, and potentially the execution of arbitrary code.
    Additionally, access-deny settings can be evaded by appending a final /
    to a URL.
    </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-1.4.16"</code>
  </resolution>
