An update for rabbitmq-server is now available for openEuler-20.03-LTS-SP4 Security Advisory openeuler-security@openeuler.org openEuler security committee openEuler-SA-2026-4029 Final 1.0 1.0 2026-09-25 Initial 2026-09-25 2026-09-25 openEuler SA Tool V1.0 2026-09-25 rabbitmq-server security update An update for rabbitmq-server is now available for openEuler-20.03-LTS-SP4 RabbitMQ is an implementation of AMQP, the emerging standard for high performance enterprise messaging. The RabbitMQ server is a robust and scalable implementation of an AMQP broker. Security Fix(es): 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) RabbitMQ is a messaging and streaming broker. Prior to 3.13.14, 4.0.19, 4.1.10, and 4.2.5, the rabbitmq_management HTTP API accepts oversized valid JSON bodies on with_decode and direct_request paths because read_complete_body checks the accumulated size before the final chunk but not the final combined size. This issue is fixed in versions 3.13.14, 4.0.19, 4.1.10, and 4.2.5.(CVE-2026-57212) An update for rabbitmq-server is now available for openEuler-20.03-LTS-SP4. openEuler Security has rated this update as having a security impact of high.
