Google Releases Chrome 22 and Pays Out Nearly $30K in Rewards

Google has released Chrome 22, a major new version of its browser that includes a huge number of security fixes, many of them high-priority vulnerabilities. The company also handed out nearly $30,000 in rewards to security researchers, more than half of it to Sergey Glazunov, who discovered two especially severe bugs that the Chrome security team deemed worthy of special rewards.

Google ChromeGoogle has released Chrome 22, a major new version of its browser that includes a huge number of security fixes, many of them high-priority vulnerabilities. The company also handed out nearly $30,000 in rewards to security researchers, more than half of it to Sergey Glazunov, who discovered two especially severe bugs that the Chrome security team deemed worthy of special rewards.

Chrome 22 includes patches for 42 individual vulnerabilities and 15 of them are listed as high-severity flaws. There also is one critical vulnerability, which earned Glazunov an extraordinary $10,000 reward from Google. That vulnerability is a universal cross-site scripting bug in frame handling. Glazunov also discovered a UXSS in the V8 engine in Chrome that earned him $5,000. 

Typically, Google’s top reward for security researchers is $3133.70, but the company’s security team recently announced that it would be giving out some higher rewards in special cases, such as when researchers find a bug that’s outside of Chrome or when the vulnerability is particularly severe.For Glazunov, a regular beneficiary of Google’s bug-bounty largess, this has already turned out to be a boon. Google also handed out a second $5,000 reward, this one to Eetu Luodemaa and Joni Vahamaki for a memory-corruption bug in the Windows kernel.
