Patch Available for "Office 2000 UA Control" Vulnerability

Originally Posted: May 12, 2000

Summary
=======
Microsoft has released a patch that eliminates a security
vulnerability in Microsoft(r) Office 2000 and Office 2000 family
members. The vulnerability could allow a malicious web site operator
to take inappropriate action on the computer of a user who visited his
web site.

Frequently asked questions regarding this vulnerability
and the patch can be found at
http://www.microsoft.com/technet/security/bulletin/fq00-034.asp

Issue
=====
An ActiveX control that ships as part of Office 2000 is incorrectly
marked as "safe for scripting". This control, the Office 2000 UA
Control, is used by the "Show Me" function in Office Help, and allows
Office functions to be scripted. A malicious web site operator could
use the control to carry out Office functions on the machine of a user
who visited his site.

The control ships only as part of Office 2000 (and Office 2000 family
members, as listed below). The patch removes all unsafe functionality,
with the result that the "Show Me" function will be disabled in Office
2000.

Affected Software Versions
==========================
 - Office 2000

Note: The products in the Office suite also are available for purchase
separately. The control ships as part of the following such products:
    - Word 2000
    - Excel 2000
    - Powerpoint 2000
    - Access 2000
    - Photodraw 2000
    - FrontPage 2000
    - Project 2000
