    As usual, our ongoing internal security work was responsible for a wide range of fixes:
    [1105224] Various fixes from internal audits, fuzzing and other initiatives

Many of the vulnerabilities have been identified using AddressSanitizer, MemorySanitizer, UndefinedBehaviorSanitizer, Control Flow Integrity, libFuzzer or AFL.

Chrome version84.0.4147.89 for Windows, Mac and Linux will be rolled out to the systems via the automatic update function in the next days. You can also download this build here. Updates for Edge, Vivaldi and other clones will probably follow soon. (via)

    Wonderful but one critical error is still disclosed by Browser Audit.

    ** Block – cookie set by JavaScript should not be sent over HTTP. **

    I am not dead certain of the possible negative effects of this but presumably such a cookie should be transmitted as encrypted.

    Firefox performs much better than Google Chrome when examined by Browser Audit. There are presently no critical errors for a start.
