PublishedIn github.com/pion/dtls/v3 before 3.1.4, MessageServerKeyExchange.Unmarshal does not verify that data remains after parsing the PSK identity hint when handling ECDHE_PSK key exchange messages. A remote peer sending a crafted ServerKeyExchange message where the PSK hint consumes all remaining data triggers an index out of range runtime panic, causing a denial of service.
