Title

The at.deny file must be group-owned by root, bin, sys, or other. (Cat II impact)

Discussion

If the group-owner of the at.deny file is not set to root, bin, sys, other, or cron, unauthorized users could be allowed to view or edit sensitive information contained within the file. Unauthorized modification could result in Denial of Service to authorized at users or provide unauthorized users with the ability to run at jobs.

Check Content

Check the group ownership of the file. Procedure: # ls -lL /usr/lib/cron/at.deny If the file is not group-owned by root, bin, sys, or other, this is a finding.

Fix Text

Change the group ownership of the at.deny file to root, bin, sys, or other. # chgrp root /usr/lib/cron/at.deny
