Descriptions

xorg-x11-server before 1.19.5 was missing length validation in X-Resource extension allowing malicious X client to cause X server to crash or possibly execute arbitrary code.

xorg-x11-server en versiones anteriores a la 1.19.5 no tenía una validación de longitud en la extensión X-Resource, lo que permitía que atacantes remotos permitan que el cliente malicioso X provoque que el servidor X se cierre inesperadamente o que, posiblemente, ejecute código arbitrario.

Several vulnerabilities have been discovered in the X.Org X server. An attacker who's able to connect to an X server could cause a denial of service or potentially the execution of arbitrary code. For the oldstable distribution (jessie), these problems have been fixed in version 2:1.16.4-1+deb8u2. For the stable distribution (stretch), these problems have been fixed in version 2:1.19.2-1+deb9u2.
