In this talk we discuss recent approaches that use fuzzing, symbolic execution and program synthesis, often in a synergistic way, to discover bugs and vulnerabilities in software programs. We first describe Badger, a tool that combines grey-box fuzzing with symbolic execution for discovering vulnerabilities which occur when the worst-case time or space complexity of an application is significantly higher than the average case. We then describe HyDiff, which extends Badger with a differential software analysis for detecting regression bugs in software evolution, analyzing side-channels in programs and evaluating robustness in deep neural networks. Finally we review how program synthesis techniques can be used to create correct-by-construction test programs that reveal bugs in RUST libraries.
