CyberRota Analysis
AI-GeneratedThe RabbitMQ Java client library versions prior to 5.31.0 are vulnerable to a denial-of-service attack due to improper handling of AMQP command assembly, which can lead to a client connection being terminated when a malicious broker sends a malformed payload. This vulnerability primarily affects Java and JVM-based applications that rely on this library for communication with RabbitMQ nodes. Organizations using affected versions should prioritize upgrading to version 5.31.0 or later to mitigate potential service disruptions.

Original NVD Description
The RabbitMQ Java client library allows Java and JVM-based applications to connect to and interact with RabbitMQ nodes. Prior to 5.31.0, inbound AMQP command assembly in src/main/java/com/rabbitmq/client/impl/CommandAssembler.java processes a content-bearing method and header whose remainingBodyBytes value is smaller than a following AMQP.FRAME_BODY payload. CommandAssembler.consumeBodyFrame subtracts the peer-controlled payload length before validating that it fits, drives remainingBodyBytes negative, and throws a raw UnsupportedOperationException instead of MalformedFrameException. A malicious or compromised broker peer can send this malformed sequence on an open nonzero channel to terminate frame processing and close the client connection, causing denial of service for work using that connection. This issue is fixed in version 5.31.0.
