A very serious flaw in Windows XP has been discovered by eEye Digital Security. Actually the flaw was discovered in July 2003, but Microsoft has just now gone public with it and is offering a patch through Windows update. Marc Maiffret of eEye told us last night on The Screen Savers that it is among the most serious Windows flaws ever because it effects all users of NT/2000/XP and very many programs on the platform. It's hard to believe, considering the magnitude of this flaw, that Microsoft has been sitting on the fix for over 200 days.
In any event, now that the hole is known, it's very important that all users of Windows NT, 2000, and XP patch immediately. Run Windows update or use IE and visit the Windows Update Site right now.
