Google fixes Pwnium vulnerabilities in Chrome 18

While enabling hardware accelerated 2D rendering

SOFTWARE DEVELOPER Google has released Chrome 18 into the stable channel, bringing a number of security fixes for vulnerabilities that were highlighted at the Pwnium competition.

Google's Chrome web browser was well and truly beaten into submission at the Pwnium competition earlier this month, with Google handing over large amounts of cash to talented security researchers. Now the firm has incorporated fixes for those security vulnerabilities among others and improved performance for Canvas2D and WebGL.

Google outlined some of the cash bounties it paid for particular fixes, with two vulnerabilities netting $1,000 apiece for two researchers. The firm also thanked four researchers for stopping security regressions from entering Chrome's stable channel, and it handed out $8,000 in additional rewards for this.

Aside from security fixes, Google has enabled GPU accelerated Canvas2D on those machines running Windows and Mac OS X that are up to the task. The firm has also enabled a Swiftshader, a software rasteriser, for users that do not have hardware that can accelerate WebGL.

Google's Chrome web browser has achieved significant market share growth in the past three years with the firm aggressively updating it. With the company pushing Chrome 18 into the stable channel, it has already announced Chrome 19 is in the beta channel, though there is no date yet for moving that over to the stable channel. µ
