Package : wpa
CVE ID : CVE-2017-13077 CVE-2017-13078 CVE-2017-13079 CVE-2017-13080

CVE-2017-13088
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 applies 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.
CVE-2017-13077: reinstallation of the pairwise key in the Four-way handshake
CVE-2017-13078: reinstallation of the group key in the Four-way handshake
CVE-2017-13079: reinstallation of the integrity group key in the Four-way
handshake
CVE-2017-13080: reinstallation of the group key in the Group Key handshake
CVE-2017-13081: reinstallation of the integrity group key in the Group Key
handshake
