| Package | Affected versions | Patched versions |

| dnsdist | ≥ 1.9.0, < 1.9.12≥ 2.0.0, < 2.0.3 | 1.9.122.0.3 |
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.
