GHSA-w93h-8xj5-rq44

GHSA-w93h-8xj5-rq44 PUBLISHED CVSS 7.5 HIGH

Record from GitHub Advisory Database · Published May 24, 2022

An issue has been found in PowerDNS Recursor before 4.1.18, 4.2.x before 4.2.5, and 4.3.x before 4.3.5. A remote attacker can cause the cached records for a given name to be updated to the Bogus DNSSEC validation state, instead of their actual DNSSEC Secure state, via a DNS ANY query. This results in a denial of service for installation that always validate (dnssec=validate), and for clients requesting validation when on-demand validation is enabled (dnssec=process).
