McAfee WebShield < 4.5 MR2 Bounced Emails Format String

High

Synopsis

The remote host is vulnerable to a remote 'format string' flaw.

Description

The remote host is running the McAfee WebShield SMTP server. This version of WebShield is vulnerable to a flaw in the way that it processes 'bounced' emails. An attacker can send a malformed email that, upon being bounced, will overflow the remote mail server.

Solution

Upgrade to version 4.5 MR2 or higher.
