CVE-2022-32189 is an uncontrolled resource-consumption vulnerability in Go's math/big package. In Go versions before 1.17.13 and 1.18.5, Float.GobDecode and Rat.GobDecode can panic when decoding an encoded big.Float or big.Rat message that is too short. An attacker who can cause an application to process such malformed encoded data may crash the affected process and deny service.
