DESCRIPTION:
A vulnerability has been reported in Microsoft Word and Works Suite,
which can be exploited by malicious people to execute arbitrary code
on a user's system automatically.

The vulnerability is caused due to an error when checking the
properties of modified documents thus making it possible to bypass
the macro security model designed to restrict potentially malicious
macros from executing on a user's system. This can be exploited by
constructing a specially crafted document with an embedded macro and
trick a user into opening the document.

Successful exploitation allows execution of arbitrary commands on a
users system with the user's privileges via macros.
