According to its banner, the version of Squid running on the remote host is 3.x prior to 3.0.STABLE26 / 3.1.15 / 3.2.0.11. It reportedly contains a buffer overflow when parsing responses from Gopher servers that results in memory corruption and usually causes the Squid server itself to crash.

Note that Nessus has relied only on the version in the proxy server's banner, which is not updated by either of the patches the project has released to address the issue. If one of those has been applied properly and the service is restarted, consider this to be a false positive.

A vulnerability has been discovered and corrected in squid :

Buffer overflow in the gopherToHTML function in gopher.cc in the Gopher reply parser in Squid 3.0 before 3.0.STABLE26, 3.1 before 3.1.15, and 3.2 before 3.2.0.11 allows remote Gopher servers to cause a denial of service (memory corruption and daemon restart) or possibly have unspecified other impact via a long line in a response. NOTE:
This issue exists because of a CVE-2005-0094 regression (CVE-2011-3205).

Packages for 2009.0 are provided as of the Extended Maintenance Program. Please visit this link to learn more:

The updated packages have been patched to correct this issue.

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.

The remote Oracle Linux 6 host has a package installed that is affected by a vulnerability as referenced in the ELSA-2011-1293 advisory.

    [7:3.1.10-1.el6_1.1]
    - Resolves: #735447 - CVE-2011-3205 squid: buffer overflow flaw in Squid's Gopher reply parser

Tenable has extracted the preceding description block directly from the Oracle Linux security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

This update of squid3 fixes a buffer overflow vulnerability in the Gopher reply parser code (CVE-2011-3205).

The remote Solaris system is missing necessary patches to address security updates :

  - Buffer overflow in the gopherToHTML function in     gopher.cc in the Gopher reply parser in Squid 3.0 before     3.0.STABLE26, 3.1 before 3.1.15, and 3.2 before 3.2.0.11     allows remote Gopher servers to cause a denial of     service (memory corruption and daemon restart) or     possibly have unspecified other impact via a long line     in a response.
