    <p>
    The Apache HTTP server is one of the most popular web servers on the
    Internet.

  <description>
    <p>
    Multiple vulnerabilities have been discovered in Apache:
    </p>
    <ul>
    <li>
    Dustin Kirkland reported that the mod_ssl module can leak memory when
    the client reports support for a compression algorithm (CVE-2008-1678).
    </li>
    <li>
    Ryujiro Shibuya reported that the ap_proxy_http_process_response()
    function in the mod_proxy module does not limit the number of forwarded
    interim responses (CVE-2008-2364).
    </li>
    <li>
    sp3x of SecurityReason reported a Cross-Site Request Forgery
    vulnerability in the balancer-manager in the mod_proxy_balancer module
    (CVE-2007-6420).
    </li>
    </ul>
  </description>
  <impact type="normal">
    <p>
    A remote attacker could exploit these vulnerabilities by connecting to
    an Apache httpd, by causing an Apache proxy server to connect to a
    malicious server, or by enticing a balancer administrator to connect to
    a specially-crafted URL, resulting in a Denial of Service of the Apache
    daemon.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All Apache users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose "&gt;=www-servers/apache-2.2.9"</code>
  </resolution>
