Russian works around sandbox to pull off Chrome exploit

http://en.wikipedia.org/wiki/Google_Chrome

A security researcher based in Russia pocketed a cool $60,000 from Google on Wednesday after he submitted a a "full exploit" for a vulnerability in the difficult-to-compromise Chrome browser.

The winning entry was part of the inaugural Pwnium contest, in which Google is offering up to $1 million in prizes for bug hunters who can find a way to defeat its browser's much-vaunted sandbox architecture. The competition occurs at the annual CanSecWest security conference in Vancouver, British Columbia and coincides with the well-known Pwn2Own contest, run by HP TippingPoint.

The only Pwnium victor so far has been Sergey Glazunov, a student who is a longtime contributor to Chromium and a winner of multiple bug bounties from the tech giant. He wrote the winning exploit for a fully patched Windows 7 machine that could be remotely executed if a victim simply visits a compromised website. Google patched the flaw Thursday and was auto-updating users' browsers with a new version.
