Details

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 CAN-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 CAN-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.
