It truly is a bad one but I really appreciate Kevin Day for finding/reporting this and for all the volunteer work fixing this.
All I had to do was "freebsd-update fetch install && reboot" on my systems and I could continue my day. Fleet management can be that easy for both pets and cattle. I do however feel for those who have deployed embedded systems. We can only hope the firmware vendors are on top of their game.
My HN addiction is now vindicated as I would probably not have noticed this RCE until after christmas.
This makes me very grateful and gives me a warm fuzzy feeling inside!
