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 these security fixes. Below, we highlight fixes that were contributed by external researchers, including those not already mentioned in recent release notes. Please see the Chrome Security Page for more information

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:
  • [646394] CVE-2016-5175: Various fixes from internal audits, fuzzing and other initiatives.

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