Lock the Door to Your Office Suite

Microsoft has patched six--count 'em, six--critical Microsoft Office security holes. For Windows users, these holes are "critical" only for Office 2000, and merely "important" to patch for other versions, says the company. For Mac users, Excel 2004 and Excel X are affected, with the flaws rated as "important."

The patches for the Office 2000 and Outlook 2000 holes, which leave you open to a complete takeover of your PC, automatically distribute via Microsoft Update, as do those for more recent versions including Office XP Service Pack 2 and 3. For other versions, or if you don't use Microsoft Update, get the appropriate patch and more info at Microsoft Security Bulletin MS06-012.
