The remote Oracle Linux host is missing one or more security updates.
From Red Hat Security Advisory 2017:1574 :
An update for sudo is now available for Red Hat Enterprise Linux 5
Extended Lifecycle Support, Red Hat Enterprise Linux 6, and Red Hat
Enterprise Linux 7.
Red Hat Product Security has rated this update as having a security
impact of Moderate. A Common Vulnerability Scoring System (CVSS) base
score, which gives a detailed severity rating, is available for each
vulnerability from the CVE link(s) in the References section.
The sudo packages contain the sudo utility which allows system
administrators to provide certain users with the permission to execute
privileged commands, which are used for system management purposes,
without having to log in as root.
Security Fix(es) :
* It was found that the original fix for CVE-2017-1000367 was
incomplete. A flaw was found in the way sudo parsed tty information
from the process status file in the proc filesystem. A local user with
privileges to execute commands via sudo could use this flaw to
escalate their privileges to root. (CVE-2017-1000368)
