RHSA-2004-462: squid Vulnerability Scan

Vulnerability Scan Summary
Check for the version of the squid packages

Detailed Explanation for this Vulnerability Test

An updated squid package that fixes a security vulnerability in the NTLM
authentication helper is now available.

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 ( has assigned the name CVE-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.
