Alpine: multiple wpa_supplicant packages: security update to 2.7-r1 (deprecated)

high Tenable Cloud Security Plugin ID 400524

Description

There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:

- 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. An attacker may be able to gain leaked
information from a side channel attack that can be used for full password recovery. 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)
