Pwnium 2: results and wrap-up
Wednesday, October 10, 2012
As part of our ongoing effort to reward exceptional
vulnerability research
in the security community, we hosted the
Pwnium 2
competition at
Hack in the Box 2012
in Kuala Lumpur yesterday.
We’re happy to confirm that we received a valid exploit from
returning pwner
, Pinkie Pie. This pwn relies on a WebKit Scalable Vector Graphics (SVG) compromise to exploit the renderer process and a second bug in the
IPC layer
to escape the Chrome sandbox. Since this exploit depends entirely on bugs within Chrome to achieve code execution, it qualifies for our highest award level as a “full Chrome exploit,” a $60,000 prize and free Chromebook.
One of Chrome’s most effective security defenses is our
fast response time
and ability to update users with critical patches, quickly. These bugs were no exception. We started analyzing the exploit as soon as it was submitted, and in fewer than 10 hours after Pwnium 2 concluded we were updating users with a
freshly patched
version of Chrome.
We’d like to thank Pinkie Pie for his hard work in assembling another great Pwnium submission. We’ll post an in-depth look at the bugs used and subsequent mitigations once other platforms have been patched.
