WebOct 28, 2024 · Fuzzing is a way to findinputs that might lead programs to crash or exhibit unwanted behavior. It can be implemented using symbolic execution. But symbolic execution is a much wider technique, that can be used in program verification tasks … WebTo overcome this problem, we design a fast concolic execution engine, called QSYM, to support hybrid fuzzing. The key idea is to tightly integrate the symbolic emulation with the native execution using dynamic binary translation, making it possible to implement more fine-grained, so faster, instruction-level symbolic emulation. chairs that sit on the floor
