https://notcve.org/view.php?id=CVE-2022-0563
21 Feb 2022 — 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. • https://lore.kernel.org/util-linux/20220214110609.msiwlm457ngoic6w%40ws.net.home/T/#u • CWE-209: Generation of Error Message Containing Sensitive Information •

https://notcve.org/view.php?id=CVE-2021-3995
28 Jan 2022 — 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.

28 Jan 2022 — 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-2021-37600 – Gentoo Linux Security Advisory 202401-08
https://notcve.org/view.php?id=CVE-2021-37600
28 Jul 2021 — 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. ** EN DISPUTA ** Un desbordamiento de enteros en util-linux hasta la versión 2.37.1 puede potencialmente causar un desbordamiento de búfer si un atacante fuera capaz de utilizar los recursos del sistema... • https://github.com/karelzak/util-linux/commit/1c9143d0c1f979c3daf10e1c37b5b1e916c22a1c • CWE-190: Integer Overflow or Wraparound •
