Francisco Guerrero 251b0e9b91 Bound declared value length against readable bytes in CBUtil
A 32-bit length field read from the wire by CBUtil.readValue (and its
siblings) flowed directly into new byte[length] with no upper bound,
allowing an unauthenticated client to drive the JVM into
OutOfMemoryError: 'Requested array size exceeds VM limit' — and, with
the default -XX:OnOutOfMemoryError=kill -9 %p, terminate the process —
by declaring Integer.MAX_VALUE as the SASL-token length in AUTH_RESPONSE.

Guard the allocation in the single private readRawBytes(ByteBuf, int)
that all int32-length readers funnel through, rejecting lengths that
exceed the buffer's readable bytes with a ProtocolException.
