Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Versions of quinn-proto from 0.5.0 before 0.11.17 are vulnerable. A peer that has completed the handshake can send a stream of empty DATAGRAM frames, which are not counted against the receive buffer limit, so memory grows until the process is killed; receiving datagrams is enabled by default. Upgrade to quinn-proto 0.11.17 or later, which counts per-datagram overhead so every queued datagram uses buffer space.
