Discussion

If a user is assigned the GID of a group not existing on the system, and a group with the GID is subsequently created, the user may have unintended rights to the group.

Check Content

Perform the following to ensure there are no GIDs referenced in /etc/passwd not defined in /etc/group:
# pwck -r
If GIDs referenced in /etc/passwd are not defined in /etc/group are returned, this is a finding.

Fix Text

Add a group to the system for each GID referenced without a corresponding group.
