"From Red Hat Security Advisory 2008:0214 :

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."
