1. Summary:
An updated squid package that fixes one security issue is now available for Red Hat Enterprise Linux 6.

3. Description:
Squid is a high-performance proxy caching server for web clients, supporting FTP, Gopher, and HTTP data objects.
A buffer overflow flaw was found in the way Squid parsed replies from remote Gopher servers. A remote user allowed to send Gopher requests to a Squid proxy could possibly use this flaw to cause the squid child process to crash or execute arbitrary code with the privileges of the squid user, by making Squid perform a request to an attacker-controlled Gopher server. (CVE-2011-3205)
Users of squid should upgrade to this updated package, which contains a backported patch to correct this issue. After installing this update, the squid service will be restarted automatically.
