<p>
Squid is a full-featured Web proxy cache designed to run on Unix-like
systems. It supports proxying and caching of HTTP, FTP, and other
protocols, as well as SSL support, cache hierarchies, transparent
caching, access control lists and many more features.

<description>
<p>
Certain malformed requests result in a segmentation fault in the
sslConnectTimeout function, handling of other certain requests trigger
assertion failures.
</p>
</description>
<impact type="normal">
<p>
By performing malformed requests an attacker could cause Squid to crash
by triggering an assertion failure or invalid memory reference.
</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-2.5.10-r2&quot;</code>
</resolution>
