CVE-2026-69219: RabbitMQ Java client ValueReader: Oversized LongString/bytes length triggers OOM via unchecked allocation
ValueReader.readBytes() allocates a byte array sized by a wire-declared content length without validating it against actual frame data. A malicious AMQP peer triggers OOM by declaring a ~2GB string/bytes field.
