Description

This security bulletin contains information about 3 secuirty vulnerabilities.

1) Information disclosure (CVE-ID: CVE-2022-37660)

The vulnerability allows a remote attacker to gain access to potentially sensitive information.

The vulnerability exists due to the way hostapd handles PKEX associations. A remote attacker can re-use public keys in order to gain access to sensitive information.

2) Use of a broken or risky cryptographic algorithm (CVE-ID: CVE-2022-23303)

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).

3) Use of a broken or risky cryptographic algorithm (CVE-ID: CVE-2022-23304)

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

The vulnerability exists due to the implementations of EAP-PWD 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 #VU23960 (CVE-2019-9495).
