Description

The vulnerability allows a remote non-authenticated attacker to manipulate or delete data.

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.


Remediation

Install update from vendor's website.
