CWE-789

Description

An attacker might be able to trick DNSdist into allocating too much memory while processing DNS over QUIC or DNS over HTTP/3 payloads, resulting in a denial of service. In setups with a large quantity of memory available this usually results in an exception and the QUIC connection is properly closed, but in some cases the system might enter an out-of-memory state instead and terminate the process.

Affected configurations

• powerdns dnsdist (>= 1.9.0 < 1.9.12) • powerdns dnsdist (>= 2.0.0 < 2.0.3)
