Synopsis: Moderate: squid security update
Issue Date: 2011-09-14
CVE Numbers: CVE-2011-3205
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.
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.
