medium Nessus Plugin ID 19713


The remote Red Hat host is missing a security update.


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.
