Security Bulletin
This security bulletin contains information about 3 vulnerabilities.
1) Input validation error
EUVDB-ID: #VU59106
Risk: Medium
CVSSv3.1: 4.6 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N/E:U/RL:O/RC:C]
CVE-ID: CVE-2021-30004
CWE-ID:
CWE-20 - Improper input validation
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to perform MitM attack.
The vulnerability exists due to insufficient validation of user-supplied input in tls/pkcs1.c and tls/x509v3.c files in wpa_supplicant and hostapd when handling AlgorithmIdentifier parameters. A remote attacker can pass specially crafted input to the application and perform MitM attack.
MitigationUpdate the affected packages.
net-wireless/hostapd to version: 2.10
Gentoo Linux: All versions
net-wireless/hostapd: before 2.10

Q & A
Can this vulnerability be exploited remotely?
Yes. This vulnerability can be exploited by a remote non-authenticated attacker via the Internet.
Is there known malware, which exploits this vulnerability?
No. We are not aware of malware exploiting this vulnerability.
2) 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 packages.

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-2022-23304
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 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).
