 * CWE: 134 Uncontrolled Format String
 * BadSource: listen_tcp Read data using a listening tcp connection
 * GoodSource: A hardcoded string
 * Sinks: printf
 *    GoodSink: dynamic printf format with string defined
 *    BadSink : dynamic printf without validation
 * Flow Variant: 53 Data flow: data passed as an argument from one method through two others to a fourth; all four functions are in different classes in the same package
