Security Fixes and Rewards

Note: Access to bug details and links may be kept restricted until a majority of users are updated with a fix. We will also retain restrictions if the bug exists in a third party library that other projects similarly depend on, but haven't yet fixed.

This update includes 50 security fixes. Below, we highlight some fixes that were either contributed by external researchers or particularly interesting. Please see the Chromium security page for more information.

We would also like to thank Atte Kettunen, cloudfuzzer and miaubiz for working with us during the development cycle to prevent security bugs from ever reaching the stable channel. $8000 in additional rewards were issued.

Many of the above bugs were detected using AddressSanitizer. The security issue in V8 is fixed in 3.20.17.7.
