The RabbitMQ Java client library allows Java and JVM-based applications to connect to and interact with RabbitMQ nodes. Prior to 5.33.1, src/main/java/com/rabbitmq/client/impl/ValueReader.java uses ValueReader.readBytes to accept a wire-declared contentLength below Integer.MAX_VALUE and allocate a byte array before checking the bytes available in the frame. A malicious AMQP peer can send a LongString or byte-array field with type tag S and a declared length such as 0x7FFFFFFE during the pre-authentication connection.start server-properties table, causing an approximately 2 GB allocation and OutOfMemoryError before readFully consumes data. The resulting memory exhaustion can terminate the JVM and cause denial of service. This issue is fixed in version 5.33.1.

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-142336 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 5.33.1, src/main/java/com/rabbitmq/client/impl/ValueReader.java uses
    ValueReader.readBytes to accept a wire-declared contentLength below Integer.MAX_VALUE and allocate a byte
    array before checking the bytes available in the frame. A malicious AMQP peer can send a LongString or
    byte-array field with type tag S and a declared length such as 0x7FFFFFFE during the pre-authentication
    connection.start server-properties table, causing an approximately 2 GB allocation and OutOfMemoryError
    before readFully consumes data. The resulting memory exhaustion can terminate the JVM and cause denial of
    service. This issue is fixed in version 5.33.1. (CVE-2026-69219)

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 5.33.1, src/main/java/com/rabbitmq/client/impl/ValueReader.java uses     ValueReader.readBytes to accept a wire-declared contentLength below Integer.MAX_VALUE and allocate a byte     array before checking the bytes available in the frame.

The resulting memory exhaustion can terminate the JVM and cause denial of     service. This issue is fixed in version 5.33.1. (CVE-2026-69219)

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