XtraMail SMTP HELO Command Remote Overflow

critical Nessus Plugin ID 10324

Synopsis

The remote host is running a mail server with a remote buffer overflow vulnerability.

Description

The remote host is running a version of XtraMail with a remote buffer overflow vulnerability. The overflow is caused by by issuing the 'HELO' command, followed by a long argument.

The HELO command is typically one of the first commands required by a mail server. The command is used by the mail server as a first attempt to allow the client to identify itself. As such, this command occurs before there is any authentication or validation of mailboxes, etc.

This issue may allow an attacker to crash the mail server, or possibly execute arbitrary code.

Solution

Contact the vendor for a patch.
