All the browsers go down in pwn2own it seems

[Gary]

Well thats a few zero days, including IE10 on Windows 8, Firefox (which was updated to fix that bug already) Firefox 19.0.2 is out! Java well knife though butter it seems...

"VUPEN Security's crack on IE 10 running on Surface Pro was an eye-opener," Gorenc said. "The vulnerability was so elegant it didn't even crash the browser. They launched the process from outside the sandbox so the user wouldn't even know if they had been hacked."
