  "title": "rust-quinn-proto: Quinn is a pure-Rust, async-compatible implementation of the IETF QUIC transport protocol",
  "description": "Quinn is a pure-Rust, async-compatible implementation of the IETF QUIC transport protocol. Starting in version 0.1.0 and prior to version 0.11.15, the \u0060Assembler\u0060 component that assembles unordered stream fragments into consecutive chunks of the stream incurs some overhead for non-contiguous fragments. Readers that read from a \u0060RecvStream\u0060 in order (through an \u0060AsyncRead\u0060 impl for example) will be sensitive to peers that send fragments while leaving out early parts of the stream, and in particular, fragments with many gaps (because these cannot be defragmented). In such a scenario, the receiving connection suffers from high buffer overhead, enabling memory exhaustion. Version 0.11.15 fixes the issue.",
