1 CVE-2021-27803 DoS Exec Code 2021-02-26 2021-04-23
5.4
None Local Network Medium Not required Partial Partial Partial
A vulnerability was discovered in how p2p/p2p_pd.c in wpa_supplicant before 2.10 processes P2P (Wi-Fi Direct) provision discovery requests. It could result in denial of service or other impact (potentially execution of arbitrary code), for an attacker within radio range.
2 CVE-2019-16275 346 DoS 2019-09-12 2020-08-24
3.3
None Local Network Low Not required None None Partial
hostapd before 2.10 and wpa_supplicant before 2.10 allow an incorrect indication of disconnection in certain situations because source address validation is mishandled. This is a denial of service that should have been prevented by PMF (aka management frame protection). The attacker must send a crafted 802.11 frame from a location that is within the 802.11 communications range.
3 CVE-2019-11555 476 DoS 2019-04-26 2019-06-07
4.3
None Remote Medium Not required None None Partial
The EAP-pwd implementation in hostapd (EAP server) before 2.8 and wpa_supplicant (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 eap_server/eap_server_pwd.c and eap_peer/eap_pwd.c.
4 CVE-2019-9496 287 DoS 2019-04-17 2019-05-15
5.0
None Remote Low Not required None None Partial
An invalid authentication sequence could result in the hostapd process terminating due to missing state validation steps when processing the SAE confirm message when in hostapd/AP mode. All version of hostapd with SAE support are vulnerable. An attacker may force the hostapd process to terminate, performing a denial of service attack. Both hostapd with SAE support and wpa_supplicant with SAE support prior to and including version 2.7 are affected.
5 CVE-2016-4476 20 DoS 2016-05-09 2020-08-12
5.0
None Remote Low Not required None None Partial
hostapd 0.6.7 through 2.5 and wpa_supplicant 0.6.7 through 2.5 do not reject \n and \r characters in passphrase parameters, which allows remote attackers to cause a denial of service (daemon outage) via a crafted WPS operation.
6 CVE-2015-8041 189 DoS Overflow 2015-11-09 2018-10-30
5.0
None Remote Low Not required None None Partial
Multiple integer overflows in the NDEF record parser in hostapd before 2.5 and wpa_supplicant before 2.5 allow remote attackers to cause a denial of service (process crash or infinite loop) via a large payload length field value in an (1) WPS or (2) P2P NFC NDEF record, which triggers an out-of-bounds read.
7 CVE-2015-5316 476 DoS 2018-02-21 2018-03-21
4.3
None Remote Medium Not required None None Partial
The eap_pwd_perform_confirm_exchange function in eap_peer/eap_pwd.c in wpa_supplicant 2.x before 2.6, when EAP-pwd is enabled in a network configuration profile, allows remote attackers to cause a denial of service (NULL pointer dereference and daemon crash) via an EAP-pwd Confirm message followed by the Identity exchange.
8 CVE-2015-5315 119 DoS Overflow 2018-02-21 2018-03-21
4.3
None Remote Medium Not required None None Partial
The eap_pwd_process function in eap_peer/eap_pwd.c in wpa_supplicant 2.x before 2.6 does not validate that the reassembly buffer is large enough for the final fragment when EAP-pwd is enabled in a network configuration profile, which allows remote attackers to cause a denial of service (process termination) via a large final fragment in an EAP-pwd message.
9 CVE-2015-5314 119 DoS Overflow 2018-02-21 2018-03-21
4.3
None Remote Medium Not required None None Partial
The eap_pwd_process function in eap_server/eap_server_pwd.c in hostapd 2.x before 2.6 does not validate that the reassembly buffer is large enough for the final fragment when used with (1) an internal EAP server or (2) a RADIUS server and EAP-pwd is enabled in a runtime configuration, which allows remote attackers to cause a denial of service (process termination) via a large final fragment in an EAP-pwd message.
