      "value": "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 permits ValueReader.readTable and ValueReader.readArray to call ValueReader.readFieldValue recursively for AMQP table type F and AMQP array type A values without a nesting-depth limit. A malicious AMQP server or network intermediary can send approximately 580 nested table levels in the pre-authentication connection.start frame, fitting within the default 131072-byte frame maximum, to trigger StackOverflowError. The error terminates the client input processing thread and causes denial of service. This issue is fixed in version 5.33.1."

Antes de la versión 5.33.1, src/main/java/com/rabbitmq/client/impl/ValueReader.java permite que ValueReader.readTable y ValueReader.readArray llamen a ValueReader.readFieldValue recursivamente para valores de tipo de tabla AMQP F y de tipo de array AMQP A sin un límite de profundidad de anidamiento. Un servidor AMQP malicioso o un intermediario de red puede enviar aproximadamente 580 niveles de tabla anidados en el marco connection.start de pre-autenticación, que cabe dentro del máximo de marco predeterminado de 131072 bytes, para desencadenar un StackOverflowError. El error termina el hilo de procesamiento de entrada del cliente y causa denegación de servicio. Este problema se corrige en la versión 5.33.1."
