Descriptions
In X.Org Server (aka xserver and xorg-server) before 1.19.4, a local attacker authenticated to the X server could overflow a global buffer, causing crashes of the X server or potentially other problems by injecting large or malformed XKB related atoms and accessing them via xkbcomp.
En versiones anteriores a la 1.19.4 de X.Org Server (también llamado xserver y xorg-server) un atacante autenticado en el servidor X podría provocar un desbordamiento de búfer global, causando cierres inesperados del servidor X o dando lugar a otros posibles problemas mediante la inyección de átomos relacionados con XKB grandes o mal formados y accediendo a ellos mediante xkbcomp.
