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