Got error when I tried to fuzz the target_programs just like examples #2

After finished install all the dependent python library, I tried to fuzz the binary in target_programs just like the examples, and I got this error:

WARNING | 2018-06-07 09:19:28,663 | angr.engines.successors | Exit state has over 257 possible solutions.

I guessed it happened because I didn't export the AFL_PATH environment, so I tried to: export AFL_PATH=~/.virtualenvs/t-fuzz/bin, and I got same error again......

How should I do to fixed this problem? Thank you

@0n3t04ll Thanks for your feedback. Please give us some time, we are doing more tests and will look at this issue later.

I had the same issue I think its due shellphish-afl. I had some issues in applying AFL patch. So, manually built shellphish-afl, instead of pip install, disabling the patch.

I have same error. OS: Debian 9.4

benquike commented 6 years ago

@0n3t04ll @chubbymaggie @dukebarman I am having another guy testing it in a new environment. But the environment I tested it was Ubuntu 16.04. I will mention it in the documents.

Please wait for a little more.

No problem ;) I tested on Ubuntu 18 and Debian 9 with last updates

How to build shellphish-afl manually? Thanks!

I've solved this issue by installing shellphish-afl using following command:

pip install git+https://github.com/shellphish/shellphish-afl

Thanks!
