RHEL 3 : squid (RHSA-2006:0045)

Synopsis :

The remote Red Hat host is missing a security update.

Description :

Updated squid packages that fix a security vulnerability as well as
several bugs are now available.

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

Squid is a high-performance proxy caching server for Web clients,
supporting FTP, gopher, and HTTP data objects.

A denial of service flaw was found in the way squid processes certain
NTLM authentication requests. A remote attacker could send a specially
crafted NTLM authentication request which would cause the Squid server
to crash. The Common Vulnerabilities and Exposures project assigned
the name CVE-2005-2917 to this issue.

Several bugs have also been addressed in this update :

* An error introduced in 2.5.STABLE3-6.3E.14 where Squid can crash if
a user visits a site which has a long DNS record.

* Some authentication helpers were missing needed setuid rights.

* Squid couldn't handle a reply from a HTTP server when the reply
began with the new-line character or wasn't HTTP/1.0 or HTTP/1.1
compliant.

* User-defined error pages were not kept when the squid package was
upgraded.

All users of squid should upgrade to these updated packages, which
contain backported patches to resolve these issues.
