This is NOT a 0day. It is a disclosed vulnerability in full-disclosure
mode, on a mailing list (fuzzing mailing list).

I am not sure why I got this 10 times now, I thought the days of these

vulnerability called a 0day anymore.

A 0day, whatever definition you use, is used in the wild before people are
aware of it.
