This research explores the applicability of code rewriting in the contexts of data-based debloating [IOSPReD] and in enhancing fuzz testing [TOPr]. IOSPReD focuses on reducing the amount of data that is included with an application to the extent of its requirement. To this end, IOSPReD automatically tracks and packages only necessary data chunks along with its application, in a container. In particular, a reduced datastore is generated and the underlying I/O calls in the program are rewritten via I/O specialization to access the reduced data accurately. TOPr focuses on target-oriented pruning to reduce the exploration space during code execution. TOPr eliminates unnecessary code that do not lead to specific target locations. Specifically, the program code is rewritten to redirect control flow only towards paths leading to the target location. In an attempt to improve fuzz testing towards predefined target locations in code, we integrate TOPr with a popularly used directed fuzzer, AFLGo.
