"The remote host is affected by the vulnerability described in GLSA-202309-16 (wpa_supplicant, hostapd: Multiple
Vulnerabilities)

  - In wpa_supplicant and hostapd 2.9, forging attacks may occur because AlgorithmIdentifier parameters are
    mishandled in tls/pkcs1.c and tls/x509v3.c. (CVE-2021-30004)

  - The implementations of SAE in hostapd before 2.10 and wpa_supplicant 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. (CVE-2022-23303)

  - The implementations of EAP-pwd in hostapd before 2.10 and wpa_supplicant 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-2019-9495. (CVE-2022-23304)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version
number.");
