American Fuzzy Lop fork server and instrumentation for pure-Python code
As indicated in README, the instrumentation is slow at the moment. Here are some rough ideas how to speed it up: * Replace `sys.settrace()` with lower-level `PyEval_SetTrace`. * Rewrite bytecode...
The errors that afl-fuzz prints are tailored to compiled programs; they are not very helpful in the context of python-afl, especially for newcomers. Related issues: #13, #21, #22,
I get the same error when I fuzz all of tests except for target.py and target_persistent.py . But I cant solve it. I hope you can help me, Thanks!! 
I'm trying to use `python-afl`. When I run `python-afl`, it print this error. `The current memory limit (50.0 MB) is too restrictive, causing an OOM fault in the dynamic linker`...
When I use the tool to test a function which has complex input parameters, such as list, dictionary or etc, the afl fuzz would generate new inputs, but the input...
Cc: @maage The afl-cmin test fails with recent AFL++ versions: ``` ====================================================================== ERROR: tests.test_cmin.test ---------------------------------------------------------------------- Traceback (most recent call last): File "/usr/lib/python3/dist-packages/nose/case.py", line 197, in runTest self.test(*self.arg) File ".../python-afl/tests/test_cmin.py", line...
Hello everyone! Why this error does not allow me to run fuzzing? I tried to manually set the `AFL_SKIP_BIN_CHECK=1` environment variables, but it doesn't help.
This allows Python code to manually poke at the trace map, which might be useful for blackbox testing. Possible alternative to #9. Before this gets merged: - [ ] Document...
Implemented opcode tracing. This version updates hash until we do something else. So my tests/target.py generates different maps. Without this feature same ops generate just increased count and I felt...
Hey, I was wondering if the opcode tracing added with Python 3.7 might be useful: ```python def wrap(frame, event, arg): frame.f_trace_lines = False frame.f_trace_opcodes = True code = frame.f_code if...
