Descriptions

X.Org Server (aka xserver and xorg-server) before 1.16.3 and 1.17.x before 1.17.1 allows remote attackers to obtain sensitive information from process memory or cause a denial of service (crash) via a crafted string length value in a XkbSetGeometry request.

X.Org Server (también conocido como xserver y xorg-server) anterior a 1.16.3 y 1.17.x anterior a 1.17.1 permite a atacantes remotos obtener información sensible de la memoria de procesos o causar una denegación de servicio (caída) a través de un valor de longitud de cadena manipulado en una solicitud XkbSetGeometry.

A buffer overflow flaw was found in the way the X.Org server handled XkbGetGeometry requests. A malicious, authorized client could use this flaw to disclose portions of the X.Org server memory, or cause the X.Org server to crash using a specially crafted XkbGetGeometry request.
