Fuzzers for coverage

Websources, these base fuzzers perform differently on different applications, while EnFuzz always outperforms other fuzzers in terms of path coverage, branch coverage and bug discovery. Furthermore, EnFuzz found 60 new vulnerabilities in several well-fuzzed projects such as libpng and libjpeg, and 44 new CVEs were assigned. 1 Introduction Webfuzzers always rely on some form of heuristics to guide their exploration. The most popular of these strategies is, by far, Coverage-Guided Fuzzing (CGF), in which the fuzzer selects inputs that try to increase some coverage metric computed over program code—typically, the number of unique edges in the control ﬂow graph.
