FreeBSD Security Advisory - FreeBSD-SA-17:07.wpa
Posted Oct 19, 2017
Authored by Mathy Vanhoef | Site security.freebsd.org

FreeBSD Security Advisory - A vulnerability was found in how a number of implementations can be triggered to reconfigure WPA/WPA2/RSN keys (TK, GTK, or IGTK) by replaying a specific frame that is used to manage the keys. Such reinstallation of the encryption key can result in two different types of vulnerabilities: disabling replay protection and significantly reducing the security of encryption to the point of allowing frames to be decrypted or some parts of the keys to be determined by an attacker depending on which cipher is used.

Ubuntu Security Notice 3455-1 - Mathy Vanhoef discovered that wpa_supplicant and hostapd incorrectly handled WPA2. A remote attacker could use this issue with using key reinstallation attacks to obtain sensitive information. Imre Rad discovered that wpa_supplicant and hostapd incorrectly handled invalid characters in passphrase parameters. A remote attacker could use this issue to cause a denial of service. Various other issues were also addressed.
