RHEL 4 : squid (RHSA-2005:766)

high Nessus Plugin ID 19713

Synopsis

The remote Red Hat host is missing one or more security updates for squid.

Description

The remote Redhat Enterprise Linux 4 host has a package installed that is affected by multiple vulnerabilities as referenced in the RHSA-2005:766 advisory.

Squid is a full-featured Web proxy cache.

A bug was found in the way Squid displays error messages. A remote attacker could submit a request containing an invalid hostname which would result in Squid displaying a previously used error message. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2004-2479 to this issue.

Two denial of service bugs were found in the way Squid handles malformed requests. A remote attacker could submit a specially crafted request to Squid that would cause the server to crash. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the names CAN-2005-2794 and CAN-2005-2796 to these issues.

Please note that CAN-2005-2796 does not affect Red Hat Enterprise Linux 2.1

Users of Squid should upgrade to this updated package that contains backported patches, and is not vulnerable to these issues.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

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

Solution

Update the RHEL squid package based on the guidance in RHSA-2005:766.
