GHSA-c5pq-fr2g-9jpf: RabbitMQ amqp091-go: Protocol Desynchronization and Frame Injection via Integer Overflow in readLongstr

**Summary** A critical stream desynchronization vulnerability has been identified in the AMQP wire-protocol parser. When parsing a long string (`readLongstr`) within a table field, providing a length that exceeds the maximum signed 32-bit integer (`2^31 - 1`, or roughly `2.1` GiB) triggers an improper error-handling condition. The parser abruptly aborts the read and returns a success status (`"",nil`) without consuming the specified bytes from the underlying network buffer. This causes all subsequent read operations to become misaligned. …
