PowerDNS Recursor Denial-of-Service Vulnerability Due to Uncontrolled Memory Allocation

A denial-of-service vulnerability has been identified in PowerDNS Recursor. An attacker can send a web request that triggers unlimited memory allocation in the internal web server, which is disabled by default. This excessive memory use can lead to service disruption.

Impact

Exploitation of this vulnerability causes a denial-of-service condition by overwhelming the internal web server with memory allocation requests, potentially leading to increased resource consumption and service unavailability.
