w1.fi wpa supplicant 2.4 vulnerabilities and exploits

(subscribe to this query)

NA

The EAP-pwd server and peer implementation in hostapd and wpa_supplicant 1.0 up to and including 2.4 allows remote malicious users to cause a denial of service (out-of-bounds read and crash) via a crafted (1) Commit or (2) Confirm message payload.

NA

The EAP-pwd server and peer implementation in hostapd and wpa_supplicant 1.0 up to and including 2.4 does not validate that a message is long enough to contain the Total-Length field, which allows remote malicious users to cause a denial of service (crash) via a crafted message.

NA

The EAP-pwd server and peer implementation in hostapd and wpa_supplicant 1.0 up to and including 2.4 does not validate a fragment is already being processed, which allows remote malicious users to cause a denial of service (memory leak) via a crafted message.

NA

The EAP-pwd peer implementation in hostapd and wpa_supplicant 1.0 up to and including 2.4 does not clear the L (Length) and M (More) flags before determining if a response should be fragmented, which allows remote malicious users to cause a denial of service (crash) via a crafted...

CVSSv3

The EAP-pwd implementation in hostapd (EAP server) prior to 2.8 and wpa_supplicant (EAP peer) prior to 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 p...

CVSSv3

The implementations of EAP-PWD in hostapd EAP Server and wpa_supplicant EAP Peer do not validate the scalar and element values in EAP-pwd-Commit. This vulnerability may allow an malicious user to complete EAP-PWD authentication without knowing the password. However, unless the cr...
