Discussion

If the skeleton files are not protected, unauthorized personnel could change user startup parameters and possibly jeopardize user files.

Check Content

Verify the skeleton files are group-owned by root, bin or sys.

Procedure:
# ls -alL /etc/skel
If a skeleton file is not group-owned by root, bin or sys this is a finding.

Fix Text

Change the group-owner of the skeleton file to root, bin or sys. 

Procedure:
# chgrp <group> /etc/skel/<skeleton file>
or:
# cd /etc/skel
# ls -L /etc/skel|xargs stat -L -c %G:%n|egrep -v "^(root|bin|sys):"|cut -d: -f2|xargs chgrp root
will change the group of all files not already in one of the approved groups to root.
