<background>
<p>
Squid is a multi-protocol proxy server.

<description>
<p>
Squid incorrectly handles TRACE requests that contain a "Max-Forwards"
header field with value "0" in the clientProcessRequest() function.
</p>
</description>
<impact type="low">
<p>
A remote attacker can send specially crafted TRACE HTTP requests that
will terminate the child process. A quickly repeated attack will lead
to a Denial of Service.
</p>
</impact>
<workaround>
<p>
There is no known workaround at this time.
</p>
</workaround>
<resolution>
<p>
All Squid users should upgrade to the latest version:
</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose &quot;&gt;=net-proxy/squid-2.6.12&quot;</code>
</resolution>
