Note: Access to bug details and links may be kept restricted until a majority of users are updated

    Patch-day rule: Google ships fixes in the advisory that discloses a bug, and this advisory states that fixed versions exist. So the vendor statement, first fix and fix for all versions all take the advisory's publication time.
