-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ===================================================================== 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.
