0a13de411157a6d6754f316e254b6eeb07a3ff7b8dc0e35d22416f744d3f50c9FreeBSD Security Advisory - A vulnerability was found in how a number of implementations can be triggered to reconfigure WPA/WPA2/RSN keys (TK, GTK, or IGTK) by replaying a specific frame that is used to manage the keys. Such reinstallation of the encryption key can result in two different types of vulnerabilities: disabling replay protection and significantly reducing the security of encryption to the point of allowing frames to be decrypted or some parts of the keys to be determined by an attacker depending on which cipher is used.
8e8f49d170cd1b8f44a0c2998b6751ff57fcd2197169fa4e32976845bd0eaf80Slackware Security Advisory - New wpa_supplicant packages are available for Slackware 14.0, 14.1, 14.2, and -current to fix security issues.
f7c456a7cfe81d5c9734a699a0a652dab3b12565a843c373d120f438a762b7deRed Hat Security Advisory 2017-2911-01 - The wpa_supplicant packages contain an 802.1X Supplicant with support for WEP, WPA, WPA2, 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: A new exploitation technique called key reinstallation attacks 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.

A remote attacker could use this issue with using key reinstallation attacks to obtain sensitive information. Imre Rad discovered that wpa_supplicant and hostapd incorrectly handled invalid characters in passphrase parameters. A remote attacker could use this issue to cause a denial of service. Various other issues were also addressed.

Those vulnerabilities applies to both the access point (implemented in hostapd) and the station (implemented in wpa_supplicant).

This research paper will be presented on at the Computer and Communications Security (CCS) conference on November 1, 2017. This paper details a flaw in the WPA2 protocol itself and most devices that makes use of WPA2 are affected.
