The remote host is affected by the vulnerability described in GLSA-202401-08 (util-linux: Multiple Vulnerabilities)

  - 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)

  - An integer overflow in util-linux through 2.37.1 can potentially cause a buffer overflow if an attacker     were able to use system resources in a way that leads to a large number in the /proc/sysvipc/sem file.
    NOTE: this is unexploitable in GNU C Library environments, and possibly in all realistic environments     (CVE-2021-37600)

  - A flaw was found in the util-linux chfn and chsh utilities when compiled with Readline support. The     Readline library uses an INPUTRC environment variable to get a path to the library config file. When the     library cannot parse the specified file, it prints an error message containing data from the file. This     flaw allows an unprivileged user to read root-owned files, potentially leading to privilege escalation.
    This flaw affects util-linux versions prior to 2.37.4. (CVE-2022-0563)

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