Cuando se cambia el tama\u00f1o de la pantalla, puede ocurrir una escritura de memoria fuera de l\u00edmites conllevando a una corrupci\u00f3n de la memoria o una denegaci\u00f3n de servicio.La mayor amenaza de esta vulnerabilidad es la disponibilidad del sistema. Debido a la naturaleza del fallo, la escalada de privilegios no puede ser totalmente descartada"
