Null pointer dereference

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 ...

CVE-2019-11555

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 ...

CVE-2019-11365

An issue was discovered in atftpd in atftp 0.7.1. A remote attacker may send a crafted packet triggering a stack-based buffer overflow due to an insecurely implemented strncpy call. The vulnerability is triggered by sending an error packet of 3 bytes or fewer. There are multiple instances of this...

CVE-2019-9498

The implementations of EAP-PWD in hostapd EAP Server, when built against a crypto library missing explicit validation on imported elements, do not validate the scalar and element values in EAP-pwd-Commit. An attacker may be able to use invalid scalar/element values to complete authentication,...

CVE-2019-9494

The implementations of SAE in hostapd and wpasupplicant are vulnerable to side channel attacks as a result of observable timing differences and cache access patterns. An attacker may be able to gain leaked information from a side channel attack that can be used for full password recovery. Both...

WPA3 design issues and implementation vulnerabilities in hostapd and wpa_supplicant

Overview Multiple vulnerabilities have been identified in WPA3 protocol design and implementations of hostapd and wpasupplicant, which can allow a remote attacker to acquire a weak password, conduct a denial of service, or gain complete authorization. These vulnerabilities have also been referred...

FreeBSD -- EAP-pwd side-channel attack

Problem Description: Potential side channel attacks in the SAE implementations used by both hostapd and wpasupplicant see CVE-2019-9494 and VU871675. EAP-pwd uses a similar design for deriving PWE from the password and while a specific attack against EAP-pwd is not yet known to be tested, there i...
