<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>
