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 6 security fixes. Below, we highlight fixes that
were contributed by external researchers. Please see the Chrome
Security Page for more information

As usual, our ongoing internal security work was responsible for a wide
range of fixes:

reaching the stable channel.
