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) Unauthorized unmount of FUSE filesystems belonging to users with similar uid. (CVE-2021-3995) Unauthorized unmount of filesystems in libmount (CVE-2021-3996) 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) Additional bug fixes included by updating to version 2.36.2. See release notes for details.
