Google unleashes Chrome 19, flattens 20 bugs

Hot fuzz spawns QuickTime patch

Google released a major update to its Chrome browser on Tuesday that tackles 20 security vulnerabilities, eight of which are classified as high-risk bugs.

Chrome 19 – a cross-platform update for Windows, Mac, Linux and Chrome Frame – also includes a number of improved features such as tab sync. Google paid security researchers more than $7,500 under its bugs bounty programme for identifying the various vulnerabilities squashed by Chrome 19.

Most of the high risk flaws patched by the new version of Chrome tackle either "out-of-bounds write" or "use-after-free" memory vulnerabilities.

The full list of vulnerabilities addressed in Chrome 19 is detailed in Google's advisory here.

In other patching news, Apple released a critical update addressing 17 security flaws in its QuickTime Media Player software. Several of the fixed vulnerabilities might lend themselves to attacks that plant malware onto the systems of users running pre-update versions of Apple's media player software. QuickTime 7.7.2 addresses a total of 17 security bugs, as explained in Apple's advisory here.

Rodrigo Branco, director of vulnerability and malware research at Qualys, discovered one of the critical bugs during fuzzing, a process that involves supplying a range of malformed data inputs to the application and checking for problems. ®
