They don't get attacked by the wither and the wither doesn't attack undead mobs. Though to be fair they don't get damaged with smite either.
Well, this just got a whole lot more confusing: MC-162557
I guess the question at hand is: Are Ghasts undead or not? Feel free to create a report about the fact Smite does not affect them.
Okay new smite report made. MC-200937
Can also confirm this behavior in 21w40a. Here are some extra details regarding this problem.
