CVE-2014-5206

Estado: ModificadaAlta (7.2)—

La función do_remount en fs/namespace.c en el kernel de Linux hasta 3.16.1 no mantiene el bit MNT_LOCK_READONLY durante el remontaje de un montaje bind, lo que permite a usuarios locales evadir las restricciones de sólo lectura y vencer ciertos mecanismos de protección sandbox a través de un comando 'mount -o remount' dentro de un espacio para el nombre del usuario.
