As a result, a remote client can make Unbound exceed the configured &#39;quic-size&#39; limit with low-cost input. Using only one connection and two streams, each sending a declared 65535-byte length prefix and then holding the streams open, a client can already trivially make Unbound roughly allocate double that amount. This is a remote availability issue / memory-accounting bypass in the downstream DoQ implementation that leads to denial of service for new DoQ clients. This vulnerability needs Unbound to be compiled with DoQ support (&#39;--with-libngtcp2&#39;) and the &#39;quic-port&#39; to be configured for the listening interfaces.</p> <p><strong>Affected:</strong> NLnet Labs Unbound</p> <p>In NLnet Labs Unbound 1.22.0 up to and including 1.25.1, when downstream DNS-over-QUIC (DoQ) is enabled, the first two bidirectional streams on a new QUIC connection (stream_id 0 and 4) bypass the per-stream &#39;quic-size&#39; gate entirely, and large input buffers are allocated later, after only the 2-byte length prefix has been received from the initial streams.
