Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Stream reassembly in quinn-proto versions 0.11.15 up to but not including 0.11.17 can be made to exhaust receiver memory. A remote, unauthenticated peer can send small gapped stream frames that bypass the chunk-count cap added in 0.11.15, pinning roughly 3 GB of memory under default transport settings until the affected streams or connection close. Upgrade quinn-proto to 0.11.17 or later.
