"The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the
UTSA-2026-142335 advisory.

    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.

Tenable has extracted the preceding description block directly from the Unity Linux security advisory.

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