The EAP-pwd implementation in hostapd (EAP server) before 2.8 and
wpa_supplicant (EAP peer) before 2.8 does not validate fragmentation
reassembly state properly for a case where an unexpected fragment could be
received. This could result in process termination due to a NULL pointer
dereference (denial of service). This affects eap_server/eap_server_pwd.c
and eap_peer/eap_pwd.c.
