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.
