If the group owner of the at.allow file is not set to root, bin, sys, or cron, unauthorized users could be allowed to view or edit the list of users permitted to run "at" jobs. 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.allow If the file is not group-owned by root, bin, sys, or cron, this is a finding.
Change the group ownership of the file. Procedure: # chgrp root /etc/at.allow
