CVEs (cve.mitre.org):	CVE-2008-1612

Details

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.

Solution

Before applying this update, make sure that all previously-released
errata relevant to your system have been applied.

This update is available via Red Hat Network. Details on how to use
