"The remote Debian 11 / 12 host has a package installed that is affected by a vulnerability as referenced in the dsa-5571
advisory.

  - RabbitMQ is a multi-protocol messaging and streaming broker. HTTP API did not enforce an HTTP request body
    limit, making it vulnerable for denial of service (DoS) attacks with very large messages. An authenticated
    user with sufficient credentials can publish a very large messages over the HTTP API and cause target node
    to be terminated by an out-of-memory killer-like mechanism. This vulnerability has been patched in
    versions 3.11.24 and 3.12.7. (CVE-2023-46118)

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