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.
