MailEnable IMAP Overflow and SMTP Vulnerabilities Vulnerability Scan

Vulnerability Scan Summary
Checks for IMAP overflow and SMTP DoS vulnerabilities in MailEnable

Detailed Explanation for this Vulnerability Test

Synopsis :

The remote mail server is affected by multiple issues.

Description :

The remote host is running a version of MailEnable Professional or
MailEnable Enterprise Edition that is prone to the following

- An IMAP Authenticate Request Buffer Overflow Vulnerability
Sending an AUTHENTICATE or LOGIN command with an argument
of 1016 characters or more overflows a stack-based buffer.
A possible hacker can leverage this flaw to overwrite sensitive
program control variables and thereby control execution
flow of the server process.

- An SMTP Malformed EHLO Request Denial Of Service Vulnerability
The SMTP service does not properly handle malformed EHLO
commands and may crash when it encounters an argument
containing the character 0x99. A remote attacker could use
this flaw to crash the SMTP service, thereby denying service
to legitimate users.

Solution :
