GoPacket's Diameter AVP decoder: uint32 underflow on vendor header size leads to unbounded ~4 GiB allocation (unauthenticated remote DoS)

Summary The Diameter AVP decoder in github.com/gopacket/gopacket computes dataLength := avp.Length - uint32headerSize without first ensuring avp.Length = headerSize. When the Vendor flag is set, headerSize is 12, but the only length guard upstream rejects avp.Length CWE-770 unbounded allocation...
