+ <h1>Problem Description:</h1>
+ <p>EAP-pwd implementation in hostapd (EAP server) and wpa_supplicant
+ (EAP peer) does 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.</p>
+ <p>See
+ https://w1.fi/security/2019-5/eap-pwd-message-reassembly-issue-with-unexpected-fragment.txt
+ for a detailed description of the bug.</p>
+ <h1>Impact:</h1>
+ <p>All wpa_supplicant and hostapd versions with EAP-pwd support could
+ suffer a denial of service attack through process termination.</p>
