Pretty hot, I'd be worried too. Use a starter? I think yeast can live up to like 140F, but a lot starts to stress and die near 120F, so you were close. My guess is that it is damaged, but will make a comeback slowly. A starter will give you a better chance. Doubt if there was enough activity while the wort was that hot to give rise to a bunch of off flavors, but just a guess. All you can do is watch and wait and have that back-up come in just in case.
