Security Bulletin
This security bulletin contains information about 4 vulnerabilities.
1) Memory leak
EUVDB-ID: #VU67550
Risk: Medium
CVSSv3.1: 6.5 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2022-38178
CWE-ID:
CWE-401 - Missing release of memory after effective lifetime
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to perform DoS attack on the target system.
The vulnerability exists due memory leak in the DNSSEC verification code for the EdDSA algorithm. A remote attacker can spoof the target resolver with responses that have a malformed EdDSA signature and perform denial of service attack.
MitigationInstall update from vendor's website.
Vulnerable software versionsIBM VIOS: 3.1.0 - 3.1.3.14

No. We are not aware of malware exploiting this vulnerability.
2) Input validation error
EUVDB-ID: #VU67548
Risk: Medium
CVSSv3.1: 6.5 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2022-3080
CWE-ID:
CWE-20 - Improper input validation
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to an error when resolvers are configured to answer from stale cache with zero stale-answer-client-timeout and there is a stale CNAME in the cache for an incoming query. A remote attacker can send a specially crafted request to the DNS resolver and perform a denial of service (DoS) attack.
