Synopsis

The remote Red Hat host is missing a security update for squid.

Description

The remote Redhat Enterprise Linux 6 host has a package installed that is affected by a vulnerability as referenced in the RHSA-2011:0545 advisory.

Squid is a high-performance proxy caching server for web clients, supporting FTP, Gopher, and HTTP data objects.

It was found that string comparison functions in Squid did not properly handle the comparisons of NULL and empty strings. A remote, trusted web client could use this flaw to cause the squid daemon to crash via a specially-crafted request. (CVE-2010-3072)

This update also fixes the following bugs:

* A small memory leak in Squid caused multiple ctx: enter level messages to be logged to /var/log/squid/cache.log. This update resolves the memory leak. (BZ#666533)

* This erratum upgrades Squid to upstream version 3.1.10. This upgraded version supports the Google Instant service and introduces various code improvements. (BZ#639365)

Users of squid should upgrade to this updated package, which resolves these issues. After installing this update, the squid service will be restarted automatically.

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

Solution

Update the RHEL squid package based on the guidance in RHSA-2011:0545.
