PowerDNS Recursor before 3.6.2 does not limit delegation chaining, which allows remote attackers to cause a denial of service ("performance degradations") via a large or infinite number of referrals, as demonstrated by resolving domains hosted by ezdns.it.

Security readout for executives and security teams

This flaw can make an affected PowerDNS Recursor spend excessive work following DNS referrals. For an organization that relies on it for name resolution, the practical risk is DNS slowdown or outage, which can disrupt applications, users, and dependent services. Exposure is likely limited to environments running PowerDNS Recursor before 3.6.2, especially recursive resolvers reachable by untrusted clients or the internet. Prioritize remediation for resolvers supporting production applications or exposed to untrusted clients. Business impact is service availability, not confirmed compromise. Mitigation focus: Upgrade PowerDNS Recursor to 3.6.2 or a vendor-supported fixed package.; Review PowerDNS and distribution advisories for any deployment-specific guidance.; Restrict recursive resolver access to trusted clients where operationally feasible..
