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 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) :

* wpa_supplicant: Unauthenticated EAPOL-Key decryption in
wpa_supplicant (CVE-2018-14526)

For more details about the security issue(s), including the impact, a
CVSS score, and other related information, refer to the CVE page(s)
listed in the References section.

This security issue was fixed :

CVE-2018-14526: Under certain conditions, the integrity of EAPOL-Key
messages was not checked, leading to a decryption oracle. An attacker
within range of the Access Point and client could have abused the
vulnerability to recover sensitive information (bsc#1104205).

The update package also includes non-security fixes. See advisory for
details.

Note that Tenable Network Security has extracted the preceding
description block directly from the SUSE security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues."
