    Package        : wpa     Version        : 2:2.9.0-21+deb11u3     CVE ID         : CVE-2022-23303 CVE-2022-23304 CVE-2022-37660

    Multiple vulnerabilities were found in wpa, a set of tools including     the widely-used wpasupplicant client for authenticating with WPA     and WPA2 wireless networks.

    CVE-2022-23303

        The implementations of SAE in hostapd         are vulnerable to side channel attacks as a result of         cache access patterns.

    CVE-2022-23304

        The implementations of EAP-pwd are vulnerable         to side-channel attacks as a result of cache access patterns.

    CVE-2022-37660

        The PKEX code remains active even after         a successful PKEX association. An attacker that successfully         bootstrapped public keys with another entity using PKEX in         the past, will be able to subvert a future bootstrapping         by passively observing public keys.

    For Debian 11 bullseye, these problems have been fixed in version     2:2.9.0-21+deb11u3.

    We recommend that you upgrade your wpa packages.

    For the detailed security status of wpa please refer to     its security tracker page at:

  - An issue was discovered in rsn_supp/wpa.c in wpa_supplicant 2.0 through 2.6. Under certain conditions, the     integrity of EAPOL-Key messages is not checked, leading to a decryption oracle. An attacker within range     of the Access Point and client can abuse the vulnerability to recover sensitive information.
    (CVE-2018-14526)

  - 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. (CVE-2019-11555)

  - The implementations of SAE and EAP-pwd in hostapd and wpa_supplicant 2.x through 2.8 are vulnerable to     side-channel attacks as a result of observable timing differences and cache access patterns when Brainpool     curves are used. An attacker may be able to gain leaked information from a side-channel attack that can be     used for full password recovery. (CVE-2019-13377)

  - The implementations of SAE in hostapd and wpa_supplicant are vulnerable to side channel attacks as a     result of observable timing differences and cache access patterns.

Both hostapd with SAE     support and wpa_supplicant with SAE support prior to and including version 2.7 are affected.
    (CVE-2019-9494)

  - The implementations of EAP-PWD in hostapd and wpa_supplicant are vulnerable to side-channel attacks as a     result of cache access patterns. All versions of hostapd and wpa_supplicant with EAP-PWD support are     vulnerable. The ability to install and execute applications is necessary for a successful attack. Memory     access patterns are visible in a shared cache. Weak passwords may be cracked. Versions of     hostapd/wpa_supplicant 2.7 and newer, are not vulnerable to the timing attack described in CVE-2019-9494.
    Both hostapd with EAP-pwd support and wpa_supplicant with EAP-pwd support prior to and including version     2.7 are affected. (CVE-2019-9495)

  - 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 attacker to complete EAP-PWD     authentication without knowing the password. However, unless the crypto library does not implement     additional checks for the EC point, the attacker will not be able to derive the session key or complete     the key exchange. Both hostapd with SAE support and wpa_supplicant with SAE support prior to and including     version 2.4 are affected. Both hostapd with EAP-pwd support and wpa_supplicant with EAP-pwd support prior     to and including version 2.7 are affected. (CVE-2019-9497)

  - 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, gaining session key     and network access without needing or learning the password. Both hostapd with SAE support and     wpa_supplicant with SAE support prior to and including version 2.4 are affected. Both hostapd with EAP-pwd     support and wpa_supplicant with EAP-pwd support prior to and including version 2.7 are affected.
    (CVE-2019-9498)

  - The implementations of EAP-PWD in wpa_supplicant EAP Peer, 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 complete authentication, session key and control of the data connection with a client.
    Both hostapd with SAE support and wpa_supplicant with SAE support prior to and including version 2.4 are     affected. Both hostapd with EAP-pwd support and wpa_supplicant with EAP-pwd support prior to and including     version 2.7 are affected. (CVE-2019-9499)
