CVE-2017-13086

A new exploitation technique called key reinstallation attacks (KRACK) affecting WPA2 has been discovered. A remote attacker within Wi-Fi range could exploit this attack to decrypt Wi-Fi traffic or possibly inject forged Wi-Fi packets by reinstalling a previously used Tunneled Direct-Link Setup (TDLS) Peerkey (TPK) key during a TDLS handshake.

This issue did not affect the versions of wpa_supplicant as shipped with Red Hat Enterprise Linux 5 and 6, as it does not support TDLS.

This issue affects the versions of wpa_supplicant as shipped with Red Hat Enterprise Linux 7.
