The Microsoft Security Response Center Blog just announced that among 8 updates coming out next Tuesday, three of them are for Windows. It doesn’t specify which versions of Windows are affected, but it does say “the highest Maximum Severity rating for these is Critical”.

I would suspect that one will be a patch for the Windows MessageBox exploit, so Vista should get it. Might another be for the Vista ‘Timer/2099 Crack’? I wouldn’t consider it critical, but Microsoft probably does. They don’t specifically say that all three are critical, so maybe this one will be ‘Important’, but I believe the default update setting would download it anyway.
