CyberRota Analysis
AI-GeneratedThe `Assembler` component in Quinn, an implementation of the IETF QUIC transport protocol, is vulnerable to memory exhaustion due to high buffer overhead when processing non-contiguous stream fragments. This issue affects versions 0.1.0 to 0.11.15, particularly impacting applications that rely on ordered reading from `RecvStream`. Organizations using affected versions should prioritize upgrading to version 0.11.15 to mitigate the risk of denial-of-service conditions.

Original NVD 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 `Assembler` component that assembles unordered stream fragments into consecutive chunks of the stream incurs some overhead for non-contiguous fragments. Readers that read from a `RecvStream` in order (through an `AsyncRead` 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.
