"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," Google Chrome test engineer Krishna Govind says.
"Many of our security bugs are detected using AddressSanitizer, MemorySanitizer, Control Flow Integrity or LibFuzzer." ®
