CVE-2022-3346Network attack vector

DNS record forgery via unchecked RRSIG owner names

Published Dec 27, 2022 · Updated Apr 14, 2025

Improper DNSSEC validation in peterzen goresolver allows remote attackers to accept forged DNS records as authentic via crafted responses. The resolver uses the returned RRSIG owner name without checking that it equals the queried domain, then fetches that owner's DNSKEY and validates the forged record set with it. Exploitation requires control of a DNSSEC-signed domain and delivery of a crafted response after a victim-triggered query; successful validation corrupts DNS answer integrity without reported confidentiality or availability effects.
