There is no fixed version for RHEL:7 shadow-utils.

NVD Description

Note: Versions mentioned in the description apply only to the upstream shadow-utils package and not the shadow-utils package as distributed by RHEL. See How to fix? for RHEL:7 relevant fixed versions and status.

shadow-utils (aka shadow) 4.4 through 4.17.0 establishes a default /etc/subuid behavior (e.g., uid 100000 through 165535 for the first user account) that can realistically conflict with the uids of users defined on locally administered networks, potentially leading to account takeover, e.g., by leveraging newuidmap for access to an NFS home directory (or same-host resources in the case of remote logins by these local network users). NOTE: it may also be argued that system administrators should not have assigned uids, within local networks, that are within the range that can occur in /etc/subuid.
