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