Stable Channel Update for Desktop
Monday, June 15, 2020

The stable channel has been updated to 83.0.4103.106 for Windows, Mac, and  
Linux, which will roll out over the coming days/weeks

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

[$15000][1081350] High CVE-2020-6505: Use after free in speech. 
Reported by Khalil Zhani on 2020-05-11

[$15000][1083819] High CVE-2020-6506: Insufficient policy enforcement in WebView. 
Reported by Alesandro Ortiz on 2020-05-18

[$N/A][1086890] High CVE-2020-6507: Out of bounds write in V8.  
Reported by Sergei Glazunov of Google Project Zero on 2020-05-27

We would also like to thank all security researchers that worked with us during the  
development cycle to prevent security bugs from ever reaching the stable channel.

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

[1084009] Various fixes from internal audits, fuzzing and other initiative.

Many of our security bugs are detected using AddressSanitizer, MemorySanitizer, 
UndefinedBehaviorSanitizer, Control Flow Integrity, libFuzzer, or AFL.

A list of all changes is available in the log.
