All major browsers fall during day 2 of Pwn2Own hacking contest

A team from French vulnerability research firm Vupen hacked Google Chrome by exploiting a use-after-free vulnerability that affects both the WebKit and Blink rendering engines. The researchers then successfully bypassed Chrome’s sandbox protection to execute arbitrary code on the underlying system.

On Wednesday, the first day of the contest that takes place every year at the CanSecWest security conference in Vancouver, researchers from the same team hacked Internet Explorer 11, Firefox, Flash Player and Adobe Reader.

Another anonymous researcher presented a Chrome remote code execution exploit Thursday, but the contest judges declared it only a partial win because some details of the hack were similar to those of an exploit presented earlier at Pwnium, Google’s own hacking contest that runs aside Pwn2Own.  MORE at PCWorld
