Se han publicado versiones correctivas de X.Org Server 21.1.14 y del componente DDX (X dependiente del dispositivo) xwayland 24.1.4, que permiten el inicio de X.Org Server para la ejecuci\u00f3n de aplicaciones X11 en entornos basados en Wayland. Las nuevas versiones solucionan una vulnerabilidad (CVE-2024-9632) que podr\u00eda ser explotada para elevar privilegios en sistemas donde el servidor X se ejecuta con derechos de root, as\u00ed como para la ejecuci\u00f3n remota de c\u00f3digo en configuraciones donde se utiliza el redireccionamiento de sesi\u00f3n X11 a trav\u00e9s de SSH. <\/p>\n

El problema es causado por un desbordamiento de b\u00fafer en la funci\u00f3n _XkbSetCompatMap(), que ocurre al intentar cambiar el tama\u00f1o del b\u00fafer sym_interpret durante el procesamiento de un mapa de bits decorado de manera especial. Debido a un error al establecer un nuevo tama\u00f1o, el cambio solo afectaba al valor num_si, pero dejaba inmutable el valor size_si. El problema se manifiesta desde el lanzamiento xorg-server-1.1.1, publicado en 2006.
