NGSSoftware has reported a vulnerability in Microsoft Outlook / Exchange, which can be exploited by malicious people to compromise a vulnerable system.

The vulnerability is caused due to boundary error when decoding the Transport Neutral Encapsulation Format (TNEF) MIME attachment. This can be exploited to execute arbitrary code when the user opens or previews a specially crafted TNEF email message or when the Microsoft Exchange Server Information Store processes the message.
