Google yesterday patched 24 vulnerabilities in Chrome, and paid out $29,500 in bounties to nine researchers. The 24 vulnerabilities include one rated “critical,” Google’s highest threat ranking. The company also paid $15,000 to long-time bug contributor Sergey Glazunov for reporting a pair of critical bugs. Chrome 22, which Google started pushing to current users on Tuesday, also debuted improvements in how the browser renders 3-D web apps. Google also called out some enhancements to Chrome in preparation for the Oct. 26 launch of Windows 8 by Microsoft.”]
