Description

Incorrect permissions of the /var/spool/cron/atjobs directory could permit unauthorized users the ability to alter atjobs and run automated jobs as privileged users. Failure to set proper permissions of the /var/spool/cron/atjobs directory provides unauthorized users with the potential to access sensitive information or change the system configuration which could weaken the system's security posture.
