Description

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-2017-13087)
