No they don't have any right to do that. It's the same "right" every player has to open the arms when you jump to dispute the ball in the air. But when you accidentaly hit the opponent with it, it's a foul. The same thing happens with the goalkeeper in this situation.
Goalies don't have any "special" status besides catching the ball with hands inside the area. There's nothing like that in the FIFA rules.
The referee could understand that was a normal collision, though. But others, like the commentator in my broadcast said it was penalty since he hits the player's head violently.
