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-2017-13087)

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.");
