    <p>
    The Apache Foundation has reported that mod_python may be prone to
    Denial of Service attacks when handling a malformed
    query. Mod_python 2.7.9 was released to fix the vulnerability,
    however, because the vulnerability has not been fully fixed,
    version 2.7.10 has been released.
    </p>
    <p>
    Users of mod_python 3.0.4 are not affected by this vulnerability.
    </p>

  <impact type="low">
    <p>
    Although there are no known public exploits known for this
    exploit, users are recommended to upgrade mod_python to ensure the
    security of their infrastructure.
    </p>
  </impact>
  <workaround>
    <p>
    Mod_python 2.7.10 has been released to solve this issue; there is
    no immediate workaround.
    </p>
  </workaround>
  <resolution>
    <p>
    All users using mod_python 2.7.9 or below are recommended to
    update their mod_python installation:
    </p>
    <code>
    $> emerge sync
    $> emerge -pv ">=www-apache/mod_python-2.7.10"
    $> emerge ">=www-apache/mod_python-2.7.10"
    $> /etc/init.d/apache restart</code>
