Descriptions

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.

X.Org X server anterior a v1.13.4 y v1.4.x anterior a v1.14.1 no restringe adecuadamente el acceso a los eventos de entrada cuando se añade un nuevo dispositivo de conexión en caliente, lo cual puede permitir a atacantes cercanos obtener información sensible, como se ha demostrado mediante la lectura de contraseñas de un tty.
