Machine-written summary

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

Versions 0.11.0 up to but not including 0.11.7 of the quinn-proto crate are affected. A server that calls retry() on an incoming connection can be made to panic, either when refuse() or ignore() is called on the resulting connection after a duplicate initial packet arrives, or when accepting after certain initial packets fail to decrypt or exhaust connection IDs. The result is denial of service against an internet-facing server. Upgrade to quinn-proto 0.11.7 or later.
