Summary

A format string vulnerability in the SMTP server of McAfee WebShield 4.5 MR2 and earlier allows remote attackers to execute arbitrary code by sending a crafted email address containing format specifiers in the domain name. The flaw occurs when a bounce message is constructed without proper sanitization.
