[3.9] hostapd: EAP-pwd message reassembly issue with unexpected fragment (CVE-2019-11555)
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.
