MailEnable SMTP Service Denial of Service Vulnerabilities (ME-10044)

This script is Copyright (C) 2010-2011 Tenable Network Security, Inc.


Synopsis :

The remote mail server is prone to denial of service attacks.

Description :

The SMTP service (MESMTPC.exe) included with the version of
MailEnable on the remote host reportedly does not properly check the
length of either the email address used in a 'MAIL FROM' command or
the domain name in a 'RCPT TO' command before using it in a log
message.

A malicious attacker may be able to leverage these issues to trigger
an unhandled invalid parameter error and cause the affected SMTP
service to crash.
