Oliver awarded Real a 93rd minute penalty, which Cristiano Ronaldo converted to send Los Blancos through 4-3 on aggregate to the semi-finals.
The decision came after Juventus had almost performed a heroic comeback, scoring three unanswered goals at the Santiago Bernabeu.
Buffon, who likely played his last UEFA Champions League match, was subsequently sent off for dissent and had a go at the match official after the game.
“To award such a doubtful, or super doubtful, penalty just ahead of the final whistle and destroy the work of a team who gave absolutely everything you have to have a rubbish bin instead of your heart,” Buffon said, as quoted by the Guardian.
“A human being cannot decide the elimination of a team with such a decision. When I don’t feel I’m good enough, I put myself in a corner. He should do the same. It’s a matter of sensibility. It means you don’t know where you are, which teams are playing, you don’t know shit.”
The goalkeeper added: “You need to be prepared for a game like this. You have to watch the first leg and see that a similar foul was not punished with a penalty for Juventus in Turin. And especially you need personality to referee a game like this. If you don’t have personality, you better watch the game from the stands with your wife and your kids while eating fries. What did I say to him while I was protesting? I could say everything in that moment because when you take such decision in a certain moment of the game it means you don’t know what sport is.
“We had done something which seemed impossible. It’s a pity it ended like this, unjustly. It was one tenth of a penalty. But life goes on.”
