Machine-written summary

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

quinn-proto versions 0.6.0 up to but not including 0.11.17 are vulnerable. A peer that has completed the handshake can send repeated NEW_CONNECTION_ID frames for already-retired connection IDs, which the library queues without the usual limit, so memory use grows without bound while the peer withholds acknowledgements. Upgrade to quinn-proto 0.11.17 or later.
