GHSA-QW35-55VC-RHGJ msgpack5: Decoding negative int64 values mutates the input buffer

Impact Decoding a negative signed 64-bit integer modifies the corresponding bytes in the caller-provided input buffer. Applications that retain or reuse encoded input for integrity checks, logging, or subsequent processing may observe silently corrupted data. Positive integers and other MessagePa...
