Windows I guess it's Windows-flaw-week or something. First, we had the Internet Explorer vulnerability used in the Google attack, and now we have a bug that's been sitting undetected in Windows NT for 17 years. The bug can be used to escalate privileges, but from what I understand, it only works locally (although that isn't made clear).

So, I can imagine, if the bug was introduced in that early stage, that noone would have known about it years later.

I don't find it unlikely that NTVDM has sat pretty much untouched since NT4 - it's not the kind of subsystem that's going to need a lot of updates, since the stuff it supports is pretty much feature-frozen... and it's not the first place you'd expect to be exploitable, since the CPU handles most of the encapsulation via V86 mode.

And the exploit is nontrivial, pretty interesting piece of code ;)
