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: - Word 2000 - Excel 2000 - Powerpoint 2000 - Access 2000 - Photodraw 2000 - FrontPage 2000 - Project 2000 - Publisher 2000 - Outlook 2000 - Works 2000 Suite
NOTE: Additional security patches are available at the Microsoft Download Center
