Red Hat Security Advisory

Synopsis: Important: wpa_supplicant security update
Advisory ID: RHSA-2017:2907-01
Product: Red Hat Enterprise Linux
Advisory URL: https://access.redhat.com/errata/RHSA-2017:2907
Issue date: 2017-10-17
CVE Names: CVE-2017-13077 CVE-2017-13078 CVE-2017-13080
CVE-2017-13082 CVE-2017-13086 CVE-2017-13087
CVE-2017-13088
=====================================================================

1. Summary:

An update for wpa_supplicant 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.

2. Relevant releases/architectures:

Red Hat Enterprise Linux Client (v. 7) – x86_64
Red Hat Enterprise Linux ComputeNode (v. 7) – x86_64
Red Hat Enterprise Linux Server (v. 7) – aarch64, ppc64, ppc64le, s390x, x86_64
Red Hat Enterprise Linux Workstation (v. 7) – x86_64

3. Description:

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, CVE-2017-13088)

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.

4. Solution:

described in this advisory, refer to:
