critical Nessus Plugin ID 182401

Language:

Description

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.

Solution

All wpa_supplicant users should upgrade to the latest version:

# emerge --sync # emerge --ask --oneshot --verbose >=net-wireless/wpa_supplicant-2.10 All hostapd users should upgrade to the latest version:

# emerge --sync # emerge --ask --oneshot --verbose >=net-wireless/hostapd-2.10
