Fuzz static read files instead of cmdline target file about certfuzz

[wdormann]

I actually just did something like this recently. It's not efficient, as it creates an additional copy of the target file for each iteration, but it got the job done. I've attached a copy of the diff that would work for your case. Obviously, modify as necessary to fit your needs. The changes are trivial enough that you could probably just modify the files by hand, if you don't have patch tools in your VM.

I'll leave this open as an enhancement request.

ah many thanks !! i see your changes, i was trying to modify the seedfile_set.py function copy_file_from_origin instead but i ll try your patch. With this change we are able to fuzz much more things (and i like the speed of BFF) thanks again.

EDIT: patch tested and working fine
dont forget to delete your .pyc for recompiling with changes

I was also looking for a hardcoded file fuzz. This patch helped
