Google has fixed more than 15 vulnerabilities in Chrome and paid out nearly $35,000 in rewards to security researchers for reporting the bugs. One researcher earned an unusually large reward of $21,500 for a series of vulnerabilities he reported in Chrome.

Google Chrome 28 includes fixes for three high-risk security flaws and just one critical bug. The lone critical vulnerability is a use-after-free flaw in network sockets reported by Collin Payne. The big winner in the Google bug bounty program for this release is Andrey Labunets, who reported a pair of vulnerabilities that earned him the special reward of $21,500.

Here’s the full list of vulnerabilities fixed in Chrome 28 for Windows, Mac and Chrome Frame:
