Google has pushed put a new version of its Chrome browser, fixing a number of flaws that were exploited at the recent Pwnium browser-hacking contest.
Chrome 18 has been released to its stable channel for Windows, Mac, Linux and Chrome Frame, and also contains graphics-enhancing features.
Nine of the security fixes included in the update were demonstrated at Pwnium, with Google paying out $4,000 for the bugs' disclosure.
Google rushed out its first post-Pwnium Chrome update just days after the contest closed, providing a fix for a bug that won its discoverer, Russian student Sergey Glazunov, a $60,000 prize.
Pwnium was established to run alongside the more famous Pwn2Own browser-hacking competition, after Google realised that it would not get full disclosure of some of the bugs demonstrated at Pwn2Own.
The latest Chrome release includes the GPU-accelerated Canvas 2D element, which allows for dynamic, scriptable rendering of 2D shapes and bitmap images, as well as enabling WebGL for 3D images. Both of these have been tested in the beta version of Chrome for some time.
However, so that users whose PC lacks a modern GPU do not miss out, Google has included the SwiftShader software rendering engine in the latest update.
“Keep in mind that a software-backed WebGL implementation is never going to perform as well as one running on a real GPU, but now more users will have access to basic 3D content on the web,” said John Bauman and Brian Salomon, of Google's Chrome development team in a blog.
Chrome 18 also includes an updated version of Adobe Flash.
