Microsoft issues critical Windows security fix after tipoff from U.S. NSA

Hmm... NSA tells Microsoft about a flaw, sounds to me that, they used that flaw, somewhere important, and now wish to close the door, in order to stop a backlash against them.

NSA should follow the Israeli lead, and setup fake front companies that do these types of Revelations.

Unless... it's a double-bluff... you know, we know you know type of thing, when infact we dont know but want you to think we know... :-) Cold War Spy stuff !
