"Mathy Vanhoef of the imec-DistriNet research group of KU Leuven
discovered multiple vulnerabilities in the WPA protocol, used for
authentication in wireless networks. Those vulnerabilities apply to
both the access point (implemented in hostapd) and the station
(implemented in wpa_supplicant).

An attacker exploiting the vulnerabilities could force the vulnerable
system to reuse cryptographic session keys, enabling a range of
cryptographic attacks against the ciphers used in WPA1 and WPA2. 

More information can be found in the researchers's paper, Key
Reinstallation Attacks: Forcing Nonce Reuse in WPA2.
