The community help forum is also a great place to reach out for help or learn  
about common issues. 

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 10 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:
[1130676] Various fixes from internal audits, fuzzing and other initiatives

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.

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