An exploitable incorrect return value vulnerability exists in the mp_check function of Tarantool's Msgpuck library 1.0.3. A specially crafted packet can cause the mp_check function to incorrectly return success when trying to check if decoding a map16 packet will read outside the bounds of a buffer, resulting in a denial of service vulnerability.
