Google has issued a new version of Chrome, patching 159 security vulnerabilities and paid out more than $75,000 in bug bounties.
A total of 272 flaws have been patched, although there was no evidence and no reports that any of those issues were ever exploited by anyone.
The top bounty was $27,633.70 paid to Jüri Aedla for a vulnerability identified as CVE-2014-3188. That vulnerability could lead to remote code execution and is triggered by a number of bugs in the Google V8 JavaScript engine and the Inter-Process Communication (IPC) function. Aedla is also being awarded an additional $4,500 reward for CVE-2014-3195, which is an information leakage issue in V8.
Overall, Google has paid out over $1.25 million in bug bounties since it first began to reward researchers for reporting flaws in Chrome back in 2010.
