Vulnerability from csaf_redhat - Published: 2017-10-17 21:38 - Updated: 2024-11-22 11:34
Summary
Red Hat Security Advisory: wpa_supplicant security update
Severity
Important
Notes
Topic: 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.
Details: 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.

CVE-2017-13077

A new exploitation technique called key reinstallation attacks (KRACKs) affecting WPA2 has been discovered. A remote attacker within Wi-Fi range could exploit this attack to decrypt Wi-Fi traffic or possibly inject forged Wi-Fi packets by reinstalling a previously used pairwise key (PTK-TK) during a 4-way handshake.
