Doc Text:
A flaw was found in the Apache Thrift Python bindings, which can lead to a Denial of Service (DoS). Due to insecure default settings and a lack of limits or throttling on resource allocation, a remote unauthenticated attacker can cause excessive resource consumption. This behavior can exhaust available system resources and render the affected service unavailable.
