Google has released Chrome 27, a new version of its browser that includes a long list of security fixes, many of which are for high-risk vulnerabilities. The company handed out more than $14,000 in rewards to researchers who reported bugs fixed in the latest iteration of Chrome.

Google’s security reward program can probably be regarded as one of the more successful ones in the industry. Designed to provide incentives for security researchers to report vulnerabilities in Chrome and Chrome OS to the company privately rather than publicly disclosing them. Rewards can range from a few hundred dollars for minor flaws up to tens of thousands of dollars for especially severe issues.

None of the vulnerabilities addressed in Chrome 27 fit the latter description, with the highest payment being $3133.70 to Atte Kettunen for some memory safety issues. Chrome users should update their browsers as soon as possible to protect themselves against exploits.

Here are the bugs fixed in Chrome 27:
