    <p>
    Luigi Auriemma discovered a vulnerability in the Crossfire game
    server, in the handling of the "oldsocketmode" option when processing
    overly large requests.
    </p>
  </description>
  <impact type="high">
    <p>
    An attacker can set up a malicious Crossfire client that would
    send a large request in "oldsocketmode", resulting in a Denial of
    Service on the Crossfire server and potentially in the execution of
    arbitrary code on the server with the rights of the game server.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All Crossfire server users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose &quot;&gt;=games-server/crossfire-server-1.9.0&quot;</code>
  </resolution>
