Security fixes and rewards:

Please see the Chromium security page for more detail. Note that the referenced bugs may be kept private until a majority of our users are up to date with the fix.

Occasionally, we issue special rewards for bugs outside of Chrome, particularly where the bug is very severe and/or we are able to partially work around the issue:
