Red Hat Product Errata RHSA-2004:242 high SHIPPED_LIVE Moderate: squid security update 2004-06-09 04:00:00 UTC

Description Mark J. Cox 2004-06-08 10:30:10 UTC
A buffer overflow was found in within the NTLM authentication helper
routine.  If Squid is configured to use the NTLM authentication helper, 
a remote attacker could potentially execute arbitrary code by sending
an overly long password.  The Common Vulnerabilities and Exposures project
(cve.mitre.org) has assigned the name CAN-2004-0541 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 helper.  

Users of Squid should update to these erratum packages which contain a
backported patch are not vulnerable to this issue.
