Details

An updated Squid package that fixes security issues is now available.

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

Squid is a full-featured Web proxy cache.

A bug was found in the way Squid displays error messages. A remote attacker
could submit a request containing an invalid hostname which would result in
Squid displaying a previously used error message. The Common
Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name
CAN-2004-2479 to this issue.

Two denial of service bugs were found in the way Squid handles malformed
requests. A remote attacker could submit a specially crafted request to
Squid that would cause the server to crash. The Common Vulnerabilities and
Exposures project (cve.mitre.org) has assigned the names CAN-2005-2794 and
CAN-2005-2796 to these issues.

Please note that CAN-2005-2796 does not affect Red Hat Enterprise Linux 2.1

Users of Squid should upgrade to this updated package that contains
backported patches, and is not vulnerable to these issues.
