Name of the Vulnerable Software and Affected Versions
RabbitMQ Java client library versions prior to 5.33.1
Description
An issue exists where the
ValueReader.readBytes function in src/main/java/com/rabbitmq/client/impl/ValueReader.java allocates a byte array based on a wire-declared contentLength before verifying the actual bytes available in the frame. A malicious AMQP peer can exploit this during the pre-authentication connection.start server-properties table by sending a LongString or byte-array field with type tag S and a declared length such as 0x7FFFFFFE. This triggers an allocation of approximately 2 GB, leading to an OutOfMemoryError and subsequent JVM termination, resulting in a denial of service.Recommendations
Update to version 5.33.1.
