Estado: ModificadaBaja (2.1)—

X.Org X server before 1.13.4 and 1.4.x before 1.14.1 does not properly restrict access to input events when adding a new hot-plug device, which might allow physically proximate attackers to obtain sensitive information, as demonstrated by reading passwords from a tty.
