It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2022-2022-086 advisory.

    A logic error was found in the libmount library of util-linux in the function that allows an unprivileged     user to unmount a FUSE filesystem. This flaw allows an unprivileged local attacker to unmount FUSE     filesystems that belong to certain other users who have a UID that is a prefix of the UID of the attacker     in its string form. An attacker may use this flaw to cause a denial of service to applications that use     the affected filesystems. (CVE-2021-3995)

    A logic error was found in the libmount library of util-linux in the function that allows an unprivileged     user to unmount a FUSE filesystem. This flaw allows a local user on a vulnerable system to unmount other     users' filesystems that are either world-writable themselves (like /tmp) or mounted in a world-writable     directory. An attacker may use this flaw to cause a denial of service to applications that use the     affected filesystems. (CVE-2021-3996)

Tenable has extracted the preceding description block directly from the tested product security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
