script_tag(name:"insight", value:"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.
