Oh this is really brilliant. The fine engineers of Microsoft have turned Java, which is pretty well secured to the point where it needs permission from the VM in order to breathe or rub it's nose, into a critical exploit which gives an attacker full control over the machine. Only Microsoft could craft a way to get a machine completely cracked through one of the more secure computing platforms out there. Truly amazing.
Yeah, I know I haven't been saying much lately. Hopefully this'll make up for it. :)
