How to fix?

Upgrade Ubuntu:12.04 fuse to version 2.8.6-2ubuntu2.1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream fuse package and not the fuse package as distributed by Ubuntu. See How to fix? for Ubuntu:12.04 relevant fixed versions and status.

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.
