the stable channel.

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

    [1163626] 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.
