Description

Updated squid packages that fix a security issue are now available for Red Hat Enterprise Linux 2.1, 3, 4 and 5.

This update has been rated as having moderate security impact by the Red Hat Security Response Team.

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

A flaw was found in the way squid manipulated HTTP headers for cached objects stored in system memory. An attacker could use this flaw to cause a squid child process to exit. This interrupted existing connections and made proxy services unavailable. Note: the parent squid process started a new child process, so this attack only resulted in a temporary denial of service. (CVE-2008-1612)

Users of squid are advised to upgrade to these updated packages, which contain a backported patch to resolve this issue.
