Description :

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. Impact :
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.
