<background>
<p>
Squid is a multi-protocol proxy server.
</p>
</background>
<description>
<p>
Squid fails to correctly handle ftp:// URI's. There is also an error in
the external_acl queue which can cause an infinite looping condition.
</p>
</description>
<impact type="normal">
<p>
An attacker could attempt to retrieve a specially crafted URI via a
Squid server causing the service to crash. If an attacker could
generate a sufficiently high load on the Squid services, they could
cause a Denial of Service by forcing Squid into an infinite loop.
</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-2.6.7&quot;</code>
</resolution>
