Where issues like this relate to the OS is in the fact that the OS 
itself shouldn't be brought down by a poorly designed app.

Of course, you can shoot yourself in the foot in any OS, but an overflow 
in a local app should never take down the kernel.  Unfortunately, memory 
management in MS Windows (though it's gotten better over time) is still 
not up to par and that is what causes a number of these issues.  Not to 
mention poor system architecture and design on the part of MS.

Was it MS Windows that actually held the code that brought the system down?

Well, that depends on how far down you want to drill and where you place 
the burden of OS stability.  If you place it on the OS, then Windows is 
fair game.  If you place the burden of OS stability on the app, then 
you're foolish and don't understand OS design concepts.  :)  (said in 
jest, but then, so is most truth)

The article doesn't make the situation entirely clear.  Did the app 
intentionally restart the system and foul it?  Did the restart occur 
because the app crashed?  I'm skeptical because technical details like 
this are usually confused, mislabeled, or misreported... even 
(especially?) in tech rags.  So, who holds the burden in this case 
depends on the answers to the questions above.
