Descriptions

X.org libXt 1.1.3 and earlier does not check the return value of the XGetWindowProperty function, which allows X servers to trigger use of an uninitialized pointer and memory corruption via vectors related to the (1) ReqCleanup, (2) HandleSelectionEvents, (3) ReqTimedOut, (4) HandleNormal, and (5) HandleSelectionReplies functions.

X.org LibXt v1.1.3 y versiones anteriores no comprueba el valor devuelto por la función XGetWindowProperty, lo que permite a los servidores X el activar el uso de un puntero no inicializado y provocar una corrupción de memoria a través de vectores relacionados con las funciones (1) ReqCleanup, (2) HandleSelectionEvents, (3) ReqTimedOut, (4) HandleNormal, y (5) HandleSelectionReplies.

A flaw was found in the way the X.Org X11 libXt runtime library used uninitialized pointers. A malicious X11 server could possibly use this flaw to execute arbitrary code with the privileges of the user running an X11 client.
