  script_tag(name:"insight", value:"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.");
