In that case that's second pre-image resistance though, not collision resistance. TTBOMK that's still not possible with MD5 (though it will probably be in a few years).

Only if the attacker had no part in making the "safe" ISO image in the first place. You just cannot know. Using MD5 makes no sense whatsoever, if you don't need collision resistance, there are faster options, and if you do, it's obviously completely unsuitable.
