Security Bulletin
This security bulletin contains information about 3 vulnerabilities.
1) Information disclosure
EUVDB-ID: #VU106025
Risk: Medium
CVSSv4.0: 1.7 [CVSS:4.0/AV:N/AC:H/AT:N/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Green]
CVE-ID: CVE-2022-37660
CWE-ID:
CWE-200 - Information exposure
Exploit availability: No
DescriptionThe 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.
Update the affected package wpa to the latest version.
Vulnerable software versionsUbuntu: 20.04 - 24.10
wpasupplicant (Ubuntu package): before 2:2.9-1ubuntu4.6
hostapd (Ubuntu package): before 2:2.9-1ubuntu4.6

2) Use of a broken or risky cryptographic algorithm
EUVDB-ID: #VU59839
Risk: Low
CVSSv4.0: 1.7 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear]
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 to the latest version.
