+ <title>Squid: Multiple vulnerabilities</title>
+ <synopsis>
+ Squid contains vulnerabilities in the the code handling NTLM (NT Lan
+ Manager), Gopher to HTML, ACLs and WCCP (Web Cache Communication Protocol)
+ which could lead to ACL bypass, denial of service and arbitrary code
+ execution.

+ <p>
+ Squid is a full-featured Web proxy cache designed to run on Unix
+ systems. It supports proxying and caching of HTTP, FTP, and other URLs,
+ as well as SSL support, cache hierarchies, transparent caching, access
+ control lists and many other features.
+ </p>
+ </background>
+ <description>
+ <p>
+ Squid contains a vulnerability in the gopherToHTML function
+ (CAN-2005-0094) and incorrectly checks the 'number of caches' field
+ when parsing WCCP_I_SEE_YOU messages (CAN-2005-0095). Furthermore the
+ NTLM code contains two errors. One is a memory leak in the
+ fakeauth_auth helper (CAN-2005-0096) and the other is a NULL pointer
+ dereferencing error (CAN-2005-0097). Finally Squid also contains an
+ error in the ACL parsing code (CAN-2005-0194).
+ </p>
+ </description>
+ <impact type="normal">
+ <p>
+ With the WCCP issue an attacker could cause denial of service by
+ sending a specially crafted UDP packet. With the Gopher issue an
+ attacker might be able to execute arbitrary code by enticing a user to
+ connect to a malicious Gopher server. The NTLM issues could lead to
+ denial of service by memory consumption or by crashing Squid. The ACL
+ issue could lead to ACL bypass.
+ </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-2.5.7-r2&quot;</code>
+ </resolution>
