RHEL 2.1 / 3 / 4 : squid (RHSA-2005:766)

Synopsis :

The remote Red Hat host is missing a security update.

Description :

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 CVE-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 CVE-2005-2794 and CVE-2005-2796 to these issues.

Please note that CVE-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.
