<title>Squid: Multiple vulnerabilities</title>
|
|
<synopsis>
|
|

|
|
which could lead to Denial of Service, access control bypass, web cache and
|
|
log poisoning.

Squid is a full-featured Web proxy cache designed to run on Unix
|
|
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 other features.

<description>
|
|
<p>
|
|
Squid contains several vulnerabilities:
|
|
</p>
|
|
<ul>
|
|
<li>Buffer overflow when handling WCCP recvfrom()
|
|
(CAN-2005-0211).</li>
|
|
<li>Loose checking of HTTP headers (CAN-2005-0173 and
|
|
CAN-2005-0174).</li>
|
|
<li>Incorrect handling of LDAP login names with spaces
|
|
(CAN-2005-0175).</li>
|
|
</ul>
|
|
</description>
|
|
<impact type="normal">
|
|
<p>
|
|
An attacker could exploit:
|
|
</p>
|
|
<ul>
|
|
<li>the WCCP buffer overflow to cause Denial of Service.</li>
|
|
<li>the HTTP header parsing vulnerabilities to inject arbitrary
|
|
response data, potentially leading to content spoofing, web cache
|
|
poisoning and other cross-site scripting or HTTP response splitting
|
|
attacks.</li>
|
|
<li>the LDAP issue to login with several variations of the same login
|
|
name, leading to log poisoning.</li>
|
|
</ul>
|
|
</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 ">=net-proxy/squid-2.5.7-r5"</code>
|
