    <p>
    The Apache HTTP server is one of the most popular web servers on the
    internet. mod_ssl provides SSL v2/v3 and TLS v1 support for Apache 1.3 and
    is also included in Apache 2.
    </p>
  </background>
  <description>
    <p>
    A flaw has been found in mod_ssl where the "SSLCipherSuite" directive could
    be bypassed in certain configurations if it is used in a directory or
    location context to restrict the set of allowed cipher suites.
    </p>
  </description>
  <impact type="low">
    <p>
    A remote attacker could gain access to a location using any cipher suite
    allowed by the server/virtual host configuration, disregarding the
    restrictions by "SSLCipherSuite" for that location.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All Apache 2 users should upgrade to the latest version:
    </p>
    <code>
    # emerge sync

    # emerge -pv "&gt;=www-servers/apache-2.0.52"
    # emerge "&gt;=www-servers/apache-2.0.52"</code>
    <p>
    All mod_ssl users should upgrade to the latest version:
    </p>
    <code>
    # emerge sync

    # emerge -pv "&gt;=net-www/mod_ssl-2.8.20"
    # emerge "&gt;=net-www/mod_ssl-2.8.20"</code>
