SUSE update for wpa

1) Input validation error

EUVDB-ID: #VU40604

Risk: Medium

CVSSv3.1: 4.6 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L/E:U/RL:O/RC:C]

CVE-ID: CVE-2015-8041

CWE-ID: CWE-20 - Improper input validation

Exploit availability: No

Description

The vulnerability allows a remote non-authenticated attacker to perform service disruption.

Multiple integer overflows in the NDEF record parser in hostapd before 2.5 and wpa_supplicant before 2.5 allow remote attackers to cause a denial of service (process crash or infinite loop) via a large payload length field value in an (1) WPS or (2) P2P NFC NDEF record, which triggers an out-of-bounds read.

Mitigation

Update the affected package wpa_supplicant to the latest version.

17) Improper Authentication

EUVDB-ID: #VU23962

Risk: High

CVSSv3.1: 8.5 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2019-9497

CWE-ID: CWE-287 - Improper Authentication

Exploit availability: No

Description

The vulnerability allows a remote attacker to bypass authentication process.

The vulnerability exists due to 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. A remote attacker can complete EAP-PWD authentication without knowing the password and gain unauthorized access to the application.

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.

This vulnerability affects the following products:

hostapd with SAE support and wpa_supplicant with SAE support prior to and including version 2.4

hostapd with EAP-pwd support and wpa_supplicant with EAP-pwd support prior to and including version 2.7

Mitigation

Update the affected package wpa_supplicant to the latest version.

CVE-ID: CVE-2019-9498

CWE-ID: CWE-264 - Permissions, Privileges, and Access Controls

Exploit availability: No

Description

The vulnerability allows a remote attacker to escalate privileges on the system.

The vulnerability exists due to 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. A remote attacker can use invalid scalar/element values to complete authentication.

This vulnerability affects the following products:

hostapd with SAE support and wpa_supplicant with SAE support prior to and including version 2.4

hostapd with EAP-pwd support and wpa_supplicant with EAP-pwd support prior to and including version 2.7

Mitigation

Update the affected package wpa_supplicant to the latest version.

20) Out-of-bounds write

EUVDB-ID: #VU59104

Risk: Medium

CVSSv3.1: 6.7 [CVSS:3.1/AV:A/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H/E:P/RL:O/RC:C]

CVE-ID: CVE-2021-0326

CWE-ID: CWE-787 - Out-of-bounds write

Exploit availability: Yes

Description

The vulnerability allows a remote attacker to compromise vulnerable system.

The vulnerability exists due to a boundary error when processing untrusted input within the p2p_copy_client_info() function of p2p.c in wpa_suplicant. A remote attacker pass specially crafted input to the application, trigger out-of-bounds write and execute arbitrary code on the target system.

Mitigation

Update the affected package wpa_supplicant to the latest version.

21) Use of a broken or risky cryptographic algorithm

EUVDB-ID: #VU59839

Risk: Low

CVSSv3.1: 4.2 [CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:L/A:N/E:U/RL:O/RC:C]

CVE-ID: CVE-2022-23303

CWE-ID: CWE-327 - Use of a Broken or Risky Cryptographic Algorithm

Exploit availability: No

Description

The vulnerability allows a remote attacker to gain access to sensitive information on the target system.

The vulnerability exists due to the implementations of SAE are vulnerable to side-channel attacks as a result of cache access patterns. A remote attacker with ability to install and execute applications can crack weak passwords when memory access patterns are visible in a shared cache.

Note, this vulnerability exists due to incomplete fix for #VU23959 (CVE-2019-9494).

Mitigation

Update the affected package wpa_supplicant to the latest version.
