Name of the Vulnerable Software and Affected Versions
RabbitMQ Java client library versions prior to 5.33.1
Description
In the
ValueReader.java file, the readTable() and readArray() functions call 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, which fits within the default 131072-byte frame maximum. This triggers a StackOverflowError, which terminates the client input processing thread and results in a denial of service.Recommendations
Update to version 5.33.1.
