Synopsis

The remote host is vulnerable to a Denial of Service (DoS) attack.

Description

The remote host is running a vulnerable version of the MailEnable email server. While the details of the flaw are unknown, it is alleged that a remote attacker can create a query such that when the MailEnable server parses the query, the service crashes. Successful exploitation denies access to legitimate users.

Solution
