Title

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

Discussion

If the group-owner of the at.allow file is not set to root, sys, bin or other, 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 Content

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

Fix Text

Change the group ownership of the file. # chgrp root /usr/lib/cron/at.allow
