    <p>
    The Apache HTTP server is one of the most popular web servers on the
    Internet. The Apache module mod_rewrite provides a rule-based engine to
    rewrite requested URLs on the fly.
    </p>

  <description>
    <p>
    An off-by-one flaw has been found in Apache's mod_rewrite module by
    Mark Dowd of McAfee Avert Labs. This flaw is exploitable depending on
    the types of rewrite rules being used.
    </p>
  </description>
  <impact type="high">
    <p>
    A remote attacker could exploit the flaw to cause a Denial of Service
    or execution of arbitrary code. Note that Gentoo Linux is not
    vulnerable in the default configuration.
    </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 www-servers/apache</code>
  </resolution>
