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

[$N/A][1073602] High CVE-2020-6831: Stack buffer overflow in SCTP. Reported by
Natalie Silvanovich of Google Project Zero on 2020-04-22


[$7500][1071059] High CVE-2020-6464: Type Confusion in Blink. Reported by
Looben Yang on 2020-04-15

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:

  o [1077866] 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.
