Google has fixed nine new vulnerabilities in its Chrome browser, including six high-risk flaws. The most serious of the bugs include three separate use-after-free vulnerabilities in various parts of the browser.

As part of its researcher reward program, Google paid out $5,500 in bounties for vulnerabilities that researchers reported directly to the company. Three of the vulnerabilities fixed in Chrome 17 were reported by Sergey Glazunov and an unnamed researcher who goes by the handle PinkiePie, each of whom took home $60,000 rewards during Google’s Pwnium contest at CanSecWest earlier this month. The $5,500 paid out to researchers this time around is one of the lower totals that Google has paid in the last couple of years.

The full list of vulnerabilities fixed in Chrome is:
