"An updated squid package that fixes several security issues is now
available.

This update has been rated as having low 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 handles PUT and POST requests. It is
possible for an authorised remote user to cause a failed PUT or POST
request which can cause Squid to crash. The Common Vulnerabilities and
Exposures project (cve.mitre.org) has assigned the name CVE-2005-0718
to this issue.

A bug was found in the way Squid handles access to the cachemgr.cgi
script. It is possible for an authorised remote user to bypass access
control lists with this flaw. The Common Vulnerabilities and Exposures
project (cve.mitre.org) has assigned the name CVE-1999-0710 to this
issue.

A bug was found in the way Squid handles DNS replies. If the port
Squid uses for DNS requests is not protected by a firewall, it is
possible for a remote attacker to spoof DNS replies, possibly
redirecting a user to spoofed or malicious content. The Common
Vulnerabilities and Exposures project (cve.mitre.org) has assigned the
name CVE-2005-1519 to this issue.

Additionally, this update fixes the following bugs: - squid fails in
the unpacking of squid-2.4.STABLE7-1.21as.5.src.rpm

Users of Squid should upgrade to this updated package, which contains
backported patches to correct these issues."
