28e289fc71
Fixes the following security vulnerabilities:
EAP-pwd implementation in hostapd (EAP server) and wpa_supplicant (EAP
peer) was discovered not to validate fragmentation reassembly state
properly for a case where an unexpected fragment could be received. This
could result in process termination due to NULL pointer dereference.
For details, see the advisory:
