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 2.8.5 and earlier does not perform a chdir to / before performing a mount or umount, which allows local users to unmount arbitrary directories via unspecified vectors.
