Microsoft Security Bulletin (MS00-071)
======================================
Patch Available for "Word Mail Merge" Vulnerability
Originally posted: October 5, 2000

Summary
=======
Microsoft has released a patch that eliminates a security
vulnerability in Microsoft(r) Word 2000 and 97. The vulnerability
could allow a malicious user to run arbitrary code on a victim's
computer without their approval.

Frequently asked questions regarding this vulnerability and the patch
can be found at
http://www.microsoft.com/technet/security/bulletin/fq00-071.asp

Issue
=====
If an Access database is specified as a data source via DDE in a Word
mail merge document, macro code can run without the user's approval
when the user opens that document.

If a user could be enticed into opening a specially constructed mail
merge Word document, which was provided either as an e-mail
attachment or as a link hosted on a hostile web site, it would be
possible to cause arbitrary code to run on the user's machine. For
such an attack to succeed, the victim would also need the ability to
reach the Access database via a UNC share or file:// protocol. If the
user is behind a firewall and security best practices have been
followed, the ports required to access the database would be blocked.

 - Microsoft Word 2000
