Discussion

If the at directory has an extended ACL, unauthorized users could be allowed to view or to edit files containing sensitive information within the at directory. Unauthorized modifications could result in Denial of Service to authorized at jobs.

Check Content

Check the permissions of the directory. # ls -lLd /var/spool/cron/atjobs If the permissions include a "+", the file has an extended ACL, this is a finding.

Fix Text

Remove the optional ACL from the directory. # chacl -z /var/spool/cron/atjobs
