Google Chrome 11 Fixes Flurry of Vulnerabilities

Google has released version 11.0.696.57 of its Google browser which addresses a large number of vulnerabilities and sets a new record for the amount of money paid to security researchers as reward in a single update.
A total number of 27 vulnerabilities were patched in this release, 18 of which are rated with high severity, 6 with medium and 3 with low.

Regular Chrome security contributors Sergey Glazunov, miaubiz and kuzzcc are credited with discovering three vulnerabilities each which earned them $4,000, $2,000 and $4,000 respectively.
The total payout for this release was $16,500, which exceeds the previous records set by Chrome 8.0.552.334 in February when researchers earned $14,500.
There were no special $1,337 or $3,133.7 rewards associated with this release, but there were many $1,000, $1,500 and $2,000 ones suggesting that researchers also helped fix the bugs they found.
Five of the patched vulnerabilities were discovered by members of the Chromium development community or Google’s own security team.
We would also like to thank miaubiz, kuzzcc, Slawomir Blazek, Drew Yao and Braden Thomas of Apple Product Security and Christian Hollier for working with us during the development cycle and helping prevent bugs from ever reaching the stable channel,” Google added.
