   * CWE: 187 Partial Comparison
   * BadSource: Environment Read input from an environment variable
   * GoodSource: Provide a matching password
   * Sinks: str
   *    GoodSink: Compare the 2 passwords correctly
   *    BadSink : use strstr() to do password match, which is a partial comparison
   * Flow Variant: 64 Data flow: void pointer to data passed from one function to another in different source files
