A Dangling Pointer is a well known security flaw in many applications. When a developer writes an application, he/she usually uses pointers to many data objects. In some scenarios, the developer may accidentally use a pointer to an invalid object. In such a case, the application will enter an unintended execution flow which could lead to an application crash or other types of dangerous behaviors.
