Answer 1

Lot’s of perfectly correct answers here, but let’s also address an incorrect one, which is the one that many of the mainstream media clearly believe. Being a zero day, is all about the timing. It says nothing about how serious it is. Often news reports treat “zero day” to mean “really bad.” If there’s a potential remote code execution vulnerability that’s fixed by a patch, many news organizations will call it a zero day, even though it’s being being fixed before the bad guys have started using it.
