If the group owner of the at.deny file is not set to root, bin, sys, 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 the group ownership of the file. Procedure: # ls -lL /etc/at.deny If the file is not group-owned by root, bin, sys, or cron, this is a finding.
Change the group ownership of the at.deny file to root, sys, bin, or cron. Procedure: # chgrp root /etc/at.deny
