SUSE CVE-2012-2389

hostapd 0.7.3, and possibly other versions before 1.0, uses 0644 permissions for /etc/hostapd/hostapd.conf, which might allow local users to obtain sensitive information such as credentials...

SUSE CVE-2016-4476

hostapd 0.6.7 through 2.5 and wpasupplicant 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...

SUSE CVE-2019-5061

An exploitable denial-of-service vulnerability exists in the hostapd 2.6, where an attacker could trigger AP to send IAPP location updates for stations, before the required authentication process has completed. This could lead to different denial of service scenarios, either by causing CAM table...

AZL-7747 CVE-2022-23303 affecting package wpa_supplicant for versions less than 2.10-1

The implementations of SAE in hostapd before 2.10 and wpasupplicant before 2.10 are vulnerable to side channel attacks as a result of cache access patterns. NOTE: this issue exists because of an incomplete fix for CVE-2019-9494...

UBUNTU-CVE-2022-23303

The implementations of SAE in hostapd before 2.10 and wpasupplicant before 2.10 are vulnerable to side channel attacks as a result of cache access patterns. NOTE: this issue exists because of an incomplete fix for CVE-2019-9494...

AZL-6974 CVE-2021-30004 affecting package wpa_supplicant for versions less than 2.9-4

In wpasupplicant and hostapd 2.9, forging attacks may occur because AlgorithmIdentifier parameters are mishandled in tls/pkcs1.c and tls/x509v3.c...

wpa_supplicant and hostapd 输入验证错误漏洞

hostapd is a user space daemon for access points and authentication servers. wpasupplicant is a cross-platform WPA request program. The program supports WEP, WPA, and WPA2, among others. An input validation error vulnerability exists in wpasupplicant and hostapd 2.9, which stems from improper...

USN-4734-1 wpa vulnerabilities

It was discovered that wpasupplicant did not properly handle P2P Wi-Fi Direct group information in some situations, leading to a heap overflow. A physically proximate attacker could use this to cause a denial of service or possibly execute arbitrary code. CVE-2021-0326 It was discovered that...

CVE-2019-10064

hostapd before 2.6, in EAP mode, makes calls to the rand and random standard library functions without any preceding srand or srandom call, which results in inappropriate use of deterministic values. This was fixed in conjunction with CVE-2016-10743...

DEBIAN-CVE-2019-5061

An exploitable denial-of-service vulnerability exists in the hostapd 2.6, where an attacker could trigger AP to send IAPP location updates for stations, before the required authentication process has completed. This could lead to different denial of service scenarios, either by causing CAM table...

CVE-2019-5062

An exploitable denial-of-service vulnerability exists in the 802.11w security state handling for hostapd 2.6 connected clients with valid 802.11w sessions. By simulating an incomplete new association, an attacker can trigger a deauthentication against stations using 802.11w, resulting in a denial...

ALPINE-CVE-2019-16275

hostapd before 2.10 and wpasupplicant 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...

AZL-6972 CVE-2019-16275 affecting package wpa_supplicant for versions less than 2.9-4

USN-4098-1 wpa vulnerability

It was discovered that wpasupplicant and hostapd were vulnerable to a side channel attack against EAP-pwd. A remote attacker could possibly use this issue to recover certain passwords...

ALPINE-CVE-2019-9497

The implementations of EAP-PWD in hostapd EAP Server and wpasupplicant EAP Peer do not validate the scalar and element values in EAP-pwd-Commit. This vulnerability may allow an attacker to complete EAP-PWD authentication without knowing the password. However, unless the crypto library does not...

ALPINE-CVE-2019-9495

The implementations of EAP-PWD in hostapd and wpasupplicant are vulnerable to side-channel attacks as a result of cache access patterns. All versions of hostapd and wpasupplicant with EAP-PWD support are vulnerable. The ability to install and execute applications is necessary for a successful...
