Descriptions

The ProcSetEventMask function in difs/events.c in the xfs font server for X.Org X11R6 through X11R6.6 and XFree86 before 3.3.3 calls the SendErrToClient function with a mask value instead of a pointer, which allows local users to cause a denial of service (memory corruption and crash) or obtain potentially sensitive information from memory via a SetEventMask request that triggers an invalid pointer dereference.

La función ProcSetEventMask en DEFI/events.c en el servidor de fuentes xfs para X.Org X11R6.6 y X11R6 hasta XFree86 antes de 3.3.3 llama a la función SendErrToClient con un valor de máscara en lugar de un puntero, lo que permite a usuarios locales provocar una denegación de servicio (corrupción de memoria y caída) u obtener información sensible de la memoria a través de una solicitud SetEventMask que dispara una desreferencia de puntero no válido.
