Echo: com.rabbitmq:amqp-client: security update to 5.31.0

medium Tenable Cloud Security Plugin ID 463446

Description

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 5.31.0, 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. (CVE-2026-63335)

Solution

Update the com.rabbitmq:amqp-client library and its related packages to version 5.31.0 or later.
