5.9 (Medium) CVSS_V3 - CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H CVSS Calculator

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.
