If a waist high full toss ball hits the stump is it a our or not?

ok, wher the batsmans crease there is a line which belongs to the umpire there s where the square leg umpire judges weather it was oer waist so if the ball was over waist where the line was then his NOT OUT. the batsmen u were talkin about was standaing outside the crease so it made it harder for the umpire then he might over given it out
