Security Bulletin
This security bulletin contains information about 3 vulnerabilities.
1) 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
DescriptionThe 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). MitigationUpdate the affected package wpa_supplicant to the latest version.
Vulnerable software versionsSUSE Linux Enterprise Server: 12-SP5
wpa_supplicant-debugsource: before 2.9-23.15.1
wpa_supplicant-debuginfo: before 2.9-23.15.1
wpa_supplicant: before 2.9-23.15.1
