The remote Oracle Linux host is missing a security update.
From Red Hat Security Advisory 2017:2907 :
An update for wpa_supplicant is now available for Red Hat Enterprise
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.
The wpa_supplicant packages contain an 802.1X Supplicant with support
for WEP, WPA, WPA2 (IEEE 802.11i / RSN), and various EAP
authentication methods. They implement key negotiation with a WPA
Authenticator for client stations and controls the roaming and IEEE
802.11 authentication and association of the WLAN driver.
Security Fix(es) :
* A new exploitation technique called key reinstallation attacks
(KRACK) affecting WPA2 has been discovered. A remote attacker within
Wi-Fi range could exploit these attacks to decrypt Wi-Fi traffic or
possibly inject forged Wi-Fi packets by manipulating cryptographic
handshakes used by the WPA2 protocol. (CVE-2017-13077, CVE-2017-13078,
CVE-2017-13080, CVE-2017-13082, CVE-2017-13086, CVE-2017-13087,
Red Hat would like to thank CERT for reporting these issues. Upstream
acknowledges Mathy Vanhoef (University of Leuven) as the original
reporter of these issues.
