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.

Bugs

Notes

Author Note
tyhicks 14.04 and 12.04 are not affected since ntfs-3g is not installed setuid-root. While there is some debconf support for setting ntfs-3g as setuid-root in the packaging, libfuse refuses to cooperate when it detects that it is running in a setuid environment.
