PowerDNS before 2.9.18, when allowing recursion to a restricted range of IP addresses, does not properly handle questions from clients that are denied recursion, which could cause a "blank out" of answers to those clients that are allowed to use recursion.

Security readout for executives and security teams

This is an old PowerDNS flaw where some DNS questions from clients denied recursion could disrupt answers for clients that were allowed to recurse. The practical concern is reliability for recursive DNS service, not documented system compromise. The provided sources do not include CVSS, CWE, or active exploitation evidence. Exposure is likely limited to organizations still running PowerDNS versions before 2.9.18 with recursion enabled only for restricted client IP ranges. Modern deployments are unlikely affected unless legacy DNS servers or embedded appliances remain unpatched. Prioritize as legacy DNS reliability remediation. It is not documented as actively exploited in the provided evidence, but affected recursive DNS can impair dependent business services if old PowerDNS remains deployed. Mitigation focus: Inventory PowerDNS servers and identify versions before 2.9.18.; Upgrade affected PowerDNS deployments to 2.9.18 or later.; Review distribution advisories for supported backported fixes..
