RHEL 6 : squid (RHSA-2011:0545)

medium Nessus Plugin ID 54591

Synopsis

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

Description

An updated squid package that fixes one security issue and two bugs is now available for Red Hat Enterprise Linux 6.

The Red Hat Security Response Team has rated this update as having low security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section.

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.

Solution

Update the affected squid and / or squid-debuginfo packages.
