No wonder many critical bugs are still unpatched and being exploited in the wild.
How does that make sense?
The NSA discovering a bug but not publicising it leaves the world no different to if the NSA had never found it, or if there had been no NSA.
The NSA knew about this 2 years ago... the bug popped up 2 years ago... I don't think it takes a tin foil hat to put them together here
