Truncated msgpack fixext format data (codes 0xd4-0xd8) decoded by shamaton/msgpack library versions across v1, v2, and v3 fail to validate input buffer boundaries, triggering out-of-bounds memory reads and runtime panics that enable denial of service. Remote attackers can craft malformed msgpack payloads to crash applications using affected library versions without requiring authentication or user interaction.
