Synopsis :

The remote Oracle Linux host is missing one or more security updates.

Description :

From Red Hat Security Advisory 2017:1581 :

An update for freeradius is now available for Red Hat Enterprise Linux
7.

Red Hat Product Security has rated this update as having a security
impact of Important. 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.

FreeRADIUS is a high-performance and highly configurable free Remote
Authentication Dial In User Service (RADIUS) server, designed to allow
centralized authentication and authorization for a network.

Security Fix(es) :

* An authentication bypass flaw was found in the way the EAP module in
FreeRADIUS handled TLS session resumption. A remote unauthenticated
attacker could potentially use this flaw to bypass the inner
authentication check in FreeRADIUS by resuming an older
unauthenticated TLS session. (CVE-2017-9148)
