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.

Note: The products in the Office suite also are available for purchase
separately. The control ships as part of the following such products:
