atheris
Atheris is a coverage-guided Python fuzzing framework built on libFuzzer for finding bugs, crashes, and security vulnerabilities in pure Python code and Python C extensions. It provides AddressSanitizer integration for detecting memory corruption, buffer overflows, and use-after-free errors. Assists with writing fuzz harnesses, configuring sanitizers, managing corpora, running fuzzing campaigns, and setting up Docker-based fuzzing environments. Covers instrumentation of Python imports, parallel fuzzing with workers, corpus minimization, and troubleshooting common issues like LD_PRELOAD configuration and compiler flag setup.
