Title
Unauthenticated clients may cause OutOfMemoryError on Apache Kafka Brokers
Summary
A security vulnerability has been identified in Apache Kafka. It affects all releases since 2.8.0. The vulnerability allows malicious unauthenticated clients to allocate large amounts of memory on brokers. This can lead to brokers hitting OutOfMemoryException and causing denial of service. Example scenarios: - Kafka cluster without authentication: Any clients able to establish a network connection to a broker can trigger the issue. - Kafka cluster with SASL authentication: Any clients able to establish a network connection to a broker, without the need for valid SASL credentials, can trigger the issue. - Kafka cluster with TLS authentication: Only clients able to successfully authenticate via TLS can trigger the issue. We advise the users to upgrade the Kafka installations to one of the 3.2.3, 3.1.2, 3.0.2, 2.8.2 versions.

Esto puede conllevar a que los brokers sufran una OutOfMemoryException y causar una denegaci\u00f3n de servicio. Ejemplos de escenarios: - Cluster Kafka sin autenticaci\u00f3n: Cualquier cliente capaz de establecer una conexi\u00f3n de red con un broker puede desencadenar el problema. - Cl\u00faster Kafka con autenticaci\u00f3n SASL: Cualquier cliente capaz de establecer una conexi\u00f3n de red con un broker, sin necesidad de credenciales SASL v\u00e1lidas, puede desencadenar el problema. - Cl\u00faster Kafka con autenticaci\u00f3n TLS: S\u00f3lo los clientes capaces de autenticarse con \u00e9xito por medio de TLS pueden desencadenar el problema.
