I dont think night king's magic works at the south of the wall but in the first season a corpse attacked lord commander mormont. Unless the corpse had some intelligance to fake his undead situation and waited for the night to attack there is a problem.

IF I remember right Othor (I think was his name?) already had his eyes changed color prior to the Night's Watch carting him back to Castle Black.
