Description

The remote host is running a version of Microsoft Word that could allow arbitrary code to be run.

To succeed, the attacker would have to send a rogue Word file to a user of the remote computer and have it open it. Then the macros contained in the Word file would bypass the security model of Word, and would be executed.
