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

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:

    [1202729] Various fixes from internal audits, fuzzing and other
initiatives


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