The RabbitMQ Java client library allows Java and JVM-based applications to connect to and interact with RabbitMQ nodes. Prior to 5.33.0, the AMQP connection tuning path records the negotiated AMQP frame_max value, but src/main/java/com/rabbitmq/client/impl/SocketFrameHandler.java and NettyFrameHandlerFactory continue to validate broker-controlled frame payload lengths against maxInboundMessageBodySize because the negotiated limit is not applied consistently through setMaxInboundFramePayloadSize. A malicious or compromised broker can send a method frame larger than the negotiated frame_max during or after connection establishment, causing the client to allocate and decode a protocol-invalid frame instead of rejecting it with MalformedFrameException. The protocol violation can disrupt the affected connection and cause client-side denial of service. This issue is fixed in version 5.33.0.

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-142330 advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

There are packages installed that are affected by a vulnerability referenced in the following CVE:

  - The RabbitMQ Java client library allows Java and JVM-based applications to connect to and interact with
    RabbitMQ nodes. Prior to 5.33.0, the AMQP connection tuning path records the negotiated AMQP frame_max
    value, but src/main/java/com/rabbitmq/client/impl/SocketFrameHandler.java and NettyFrameHandlerFactory
    continue to validate broker-controlled frame payload lengths against maxInboundMessageBodySize because the
    negotiated limit is not applied consistently through setMaxInboundFramePayloadSize. A malicious or
    compromised broker can send a method frame larger than the negotiated frame_max during or after connection
    establishment, causing the client to allocate and decode a protocol-invalid frame instead of rejecting it
    with MalformedFrameException. The protocol violation can disrupt the affected connection and cause client-
    side denial of service. This issue is fixed in version 5.33.0. (CVE-2026-61634)

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - The RabbitMQ Java client library allows Java and JVM-based applications to connect to and interact with     RabbitMQ nodes. Prior to 5.33.0, the AMQP connection tuning path records the negotiated AMQP frame_max     value, but src/main/java/com/rabbitmq/client/impl/SocketFrameHandler.java and NettyFrameHandlerFactory     continue to validate broker-controlled frame payload lengths against maxInboundMessageBodySize because the     negotiated limit is not applied consistently through setMaxInboundFramePayloadSize. A malicious or     compromised broker can send a method frame larger than the negotiated frame_max during or after connection     establishment, causing the client to allocate and decode a protocol-invalid frame instead of rejecting it     with MalformedFrameException. The protocol violation can disrupt the affected connection and cause client-     side denial of service. This issue is fixed in version 5.33.0. (CVE-2026-61634)

Note that Nessus relies on the presence of the package as reported by the vendor.
