Google Chrome 8.0.552.237

(2011.01.12)

Chrome on stable channel has been updated to 8.0.552.237 for all platforms. Chrome OS has also been updated, to 8.0.552.334. These releases contain the security fixes listed below.

Security fixes and rewards:
Please see the Chromium security page for more detail. Note that the referenced bugs may be kept private until a majority of our users are up to date with the fix.

We’re delighted to offer our first “elite” $3133.7 Chromium Security Reward to Sergey Glazunov. Critical bugs are harder to come by in Chrome, but Sergey has done it. Sergey also collects a $1337 reward and several other rewards at the same time, so congratulations Sergey!

Also of note is a clarification on our default charity policy. Some researchers are unable to accept rewards, or even provide a suggestion for a charity. In such cases, it feels like a shame to lose a charitable contribution so we will default reward money to the Red Cross.
