Mozilla’s Bugzilla Hacked, Exposing Firefox Zero-Days

Mozilla admitted today that its Bugzilla bug tracking system was breached by an attacker, who was then able to get access to information about unpatched zero-day bugs. While Mozilla doesn’t have finite timelines on when the breach occurred, it may well have happened as far back as September 2013. According to Mozilla, the attacker was able to breach a user’s account that had privileged access to Bugzilla, including the non-public zero-day flaw information.
