Vulnerability Details:
	
TNEF Decoding Vulnerability - CVE-2006-0002

A remote code execution vulnerability exists in Microsoft Outlook and Microsoft
Exchange Server because of the way that it decodes the Transport Neutral
Encapsulation Format (TNEF) MIME attachment.

An attacker could exploit the vulnerability by constructing a specially crafted
TNEF message that could potentially allow remote code execution when a user
opens or previews a malicious e-mail message or when the Microsoft Exchange
Server Information Store processes the specially crafted message.

An attacker who successfully exploited this vulnerability could take complete
control of an affected system.
