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.

Weakness

The product does not properly assign, modify, track, or check privileges for an actor, creating an unintended sphere of control for that actor.

Affected Software

Name Vendor Start Version End Version
Ntfs-3g Tuxera * 2016.2.22 (including)
Ntfs-3g Ubuntu upstream *
Ntfs-3g Ubuntu xenial *
Ntfs-3g Ubuntu yakkety *
