util-linux 2.37.3 Release Notes
===============================

This release fixes two security mount(8) and umount(8) issues:

CVE-2021-3996
    Improper UID check in libmount allows an unprivileged user to unmount FUSE
    filesystems of users with similar UID.

CVE-2021-3995
    This issue is related to parsing the /proc/self/mountinfo file allows an
    unprivileged user to unmount other user's filesystems that are either
    world-writable themselves or mounted in a world-writable directory.
