Frozen Corned Beef left out to thaw,
I'd be fine with it. Salt is a preservative, and it was still cold to the touch - not the same as if it had spent 24 hours in a 70 degree F environment, or a 40 degree C environment. 

The default mantra for this site is to throw everything away. If you or someone you are feeding actually is immune compromised, this makes sense - if not, it's a rather extreme view, but that's the way the wind blows here, so that's the advice you can expect to see upvoted.
