PRSD detection denial of service
CVE-2026-33596 1 Powerdns 1 Dnsdist 2026-06-17 N/A 3.1 LOW
A client might theoretically be able to cause a mismatch between queries sent to a backend and the received responses by sending a flood of perfectly timed queries that are routed to a TCP-only or DNS over TLS backend.
CVE-2026-33595 1 Powerdns 1 Dnsdist 2026-06-17 N/A 5.3 MEDIUM

A client can trigger excessive memory allocation by generating a lot of queries that are routed to an overloaded DoH backend, causing queries to accumulate into a buffer that will not be released until the end of the connection.
