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,
