Every iteration has a 50% chance of finding the password element. This means one in every 2048 handshakes will fail, in which case an error frame is sent to the client. This event leaks information that can be abused in an offline password brute-force attack. More precisely, the adversary learns that all 10 iterations failed for the given random EAP-pwd token. Using the same techniques as in the Dragonblood attack, this can be used to brute-force the password. This patch fixes the above issue by executing enough iterations such that the password element is always found eventually. Note that timing and cache leaks remain a risk against the current implementation of EAP-pwd. Mathy Vanhoef (via Alan T.
