- Summary
- [none]
- Details
-
The EAP-pwd implementation in hostapd (EAP server) before 2.8 and wpasupplicant (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 eapserver/eapserverpwd.c and eappeer/eappwd.c.
