Google updates Chrome after successful exploit at Pwnium 2

(LiveHacking.Com) – Google has released a rapid update to its Chrome web browser after it was successfully exploited at the Google run Pwnium 2 hacking competition. Chrome 22.0.1229.94, which is available for Windows, Mac, and Linux, fixes a SVG use-after-free and IPC arbitrary file write bug that was successfully used by Pinkie Pie to fully exploit Chrome. The prize money was $60,000 which is the top amount awarded for a full Chrome exploit on a fully patched Windows 7  PC using only bugs in Chrome itself.

“We’re delighted at the success of Pwnium 2, and anticipate additional hardening and future improvements to Chrome as a result of the competition,” wrote Jason Kersey from Google’s Chrome team.

The official bug list is as follows:

  • [$60,000][154983][154987] Critical CVE-2012-5112: SVG use-after-free and IPC arbitrary file write. Credit to Pinkie Pie.

PinkiePie (aka PwniePie) is no stranger to exploiting Chrome. Back in March he also received $60,000 after successfully demonstrating an exploit at the first Pwnium competition. Shortly after Google issued 17.0.963.79 to fix the vulnerability used. At the time, Jason Kersey from the Google Chrome team is quoted as calling the exploit “a beautiful piece of work.”
