Descriptions

fusermount in FUSE before 2.9.3-15 does not properly clear the environment before invoking (1) mount or (2) umount as root, which allows local users to write to arbitrary files via a crafted LIBMOUNT_MTAB environment variable that is used by mount's debugging feature.

fusermount en FUSE anterior a 2.9.3-15 no limpia correctamente el entorno antes de llamar a (1) mount o (2) umount como root, lo que permite a usuarios locales escribir en ficheros arbitrarios a través de una variable de entorno LIBMOUNT_MTAB manipulada que es utilizada por la característica de depuración de mount.
