(RHSA-2004:462) squid security update

Squid is a full-featured Web proxy cache.

An out of bounds memory read bug was found within the NTLM authentication
helper routine. If Squid is configured to use the NTLM authentication
helper, a remote attacker could send a carefully crafted NTLM
authentication packet and cause Squid to crash. The Common Vulnerabilities
and Exposures project (cve.mitre.org) has assigned the name CAN-2004-0832
to this issue.

Note: The NTLM authentication helper is not enabled by default in Red Hat
Enterprise Linux 3. Red Hat Enterprise Linux 2.1 is not vulnerable to this
issue as it shipped with a version of Squid which did not contain the
vulnerable helper.

Users of Squid should update to this erratum package, which contains a
backported patch and is not vulnerable to this issue.
