Microsoft recommends that you use the Office Product Updates site to determine if your computer requires this update before installing it.
The Office 2000 Security Patch: KB822035 offers the highest levels of stability and security available for Microsoft Office XP. This update addresses a flaw in the way Microsoft Office uses Visual Basic for Applications (VBA) to check document properties when opening a maliciously crafted document. This flaw could allow arbitrary code to run when a user opened a specially crafted document from an attacker. This update addresses that vulnerability so that files opened using VBA are handled appropriately. The Office 2000 Security Patch: KB822035 is part of Microsoft's continued effort to provide the latest product updates to customers.
