Descriptions

Jann Horn of Google Project Zero discovered that NTFS-3G, a read-write NTFS driver for FUSE, does not scrub the environment before executing modprobe with elevated privileges. A local user can take advantage of this flaw for local root privilege escalation.

Jann Horn, de Google Project Zero, descubrió que NTFS-3G, un controlador NTFS de lectura-escritura para FUSE, no limpia en profundidad el entorno antes de ejecutar modprobe con privilegios elevados. Un usuario local puede aprovecharse de este error para escalar privilegios locales a root.

NTFS-3G has an issue where modprobe is executed with an unsanitized environment.
