+ Squid contains a bug in the function ntlm_check_auth(). It fails to do
+ proper bounds checking on the values copyied to the 'pass' variable.
+ </p>
+ </background>
+ <description>
+ <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>
+ </description>
+ <impact type="high">
+ <p>
+ If Squid is configured to use NTLM authentication, an attacker could
+ exploit this vulnerability by sending a very long password. This could lead
+ to arbitrary code execution with the permissions of the user running Squid.
+ </p>
+ </impact>
+ <workaround>
+ <p>
+ There is no known workaround at this time. All users are encouraged to
+ upgrade to the latest available version.
+ </p>
+ </workaround>
+ <resolution>
+ <p>
+ All Squid users should upgrade to the latest stable version:
+ </p>
+ <code>
+ # emerge sync
+
+ # emerge -pv ">=net-proxy/squid-2.5.5-r2"
+ # emerge ">=net-proxy/squid-2.5.5-r2"</code>
