Microsoft customers will get patches to repair critical security holes in Office and Office Web components.
In the monthly Patch Tuesday preview on its TechNet site, the software giant said it would release four critical fixes affecting Office 2000, Office Excel 2000 and Outlook.
Microsoft said the patches were rated critical since an attacker could successfully exploit the vulnerabilities remotely and execute code.
The company will also update its malicious software removal tool and offer a Webcast so customers can ask questions or air concerns.
