   * CWE: 122 Heap Based Buffer Overflow
   * BadSource:  Allocate using malloc() and set data pointer to a small buffer
   * GoodSource: Allocate using malloc() and set data pointer to a large buffer
   * Sinks: cpy
   *    BadSink : Copy string to data using strcpy
   * Flow Variant: 65 Data/control flow: data passed as an argument from one function to a function in a different source file called via a function pointer
