Google has plugged 50 security vulnerabilities in the latest update to the Chrome browser.
Among the issues fixed in Chrome 37 are a number of bugs that can be used together to break out of the Chrome sandbox and execute code remotely. That discovery earned the researcher behind it a $30,000 bug bounty. Several other vulnerabilities earned researchers between $500 and $4,000.
Here are some of the bugs fixed in the update and their associated rewards:
[$30000] Critical CVE-2014-3176, CVE-2014-3177: A special reward to [email protected] for a combination of bugs in V8, IPC, sync, and extensions that can lead to remote code execution outside of the sandbox.

“We would also like to thank Collin Payne, Christoph Diehl, Sebastian Mauer, Atte Kettunen, and cloudfuzzer for working with us during the development cycle to prevent security bugs from ever reaching the stable channel,” according to Google. “$8000 in additional rewards were issued.”
