Description:
 In FreeRADIUS 3.0 through 3.0.19, on average 1 in every 2048 EAP-pwd
 handshakes fails because the password element cannot be found within 10
 iterations of the hunting and pecking loop. This leaks information that an
 attacker can use to recover the password of any user. This information
 leakage is similar to the "Dragonblood" attack and CVE-2019-9494.
