Google spends $17,000 on Chrome browser vulnerabilities

Google has release another Chrome browser point update to fix multiple critical security vulnerabilities that affect Windows, Mac, Linux, and Chrome Frame users.

The Chrome 13.0.782.107 update, released via the browser's silent automatic update mechanism, fixes a total of 30 vulnerablities, some serious enough to allow drive-by download attacks.

The company said it paid about $17,000 in bounties to hackers who found and reported the vulnerabilities.
