CWE-264  (opens in a new tab)

How to fix?

Upgrade Debian:10 fuse to version 2.9.3-16 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 Debian. See How to fix? for Debian:10 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.
