Fizzer with Local Space Fuzzing
Martin Jonáš, Jan Strejček, Marek Trtík · Lecture notes in computer science · 2025
Abstract Fizzer is a gray-box fuzzer introduced at Test-Comp 2024. This paper summarizes the lessons learned with the original version and describes the major changes including new analyses implemented in the current version of Fizzer. In particular, Fizzer now uses dynamic taint-flow analysis and local space fuzzing. We also provide experimental results showing the progress between the two versions.
