I am getting this exact same error when trying to run on any binary. I see that the issue was marked as closed. Does anyone know how I could fix it? Thanks.

Are you able to run the ret binary without zeratool? I think that one might be a 32bit binary, so if you're using a 64bit system you'll need to install 32bit libsOn Jun 15, 2023 9:36 PM, J-Miller1 @.***> wrote: I am getting this exact same error when trying to run on any binary.

Thanks for responding so quickly. When I try to run ret I get "exec format error: challenges/ret".

But I get the same error from the original post when I run zeratool on 64bit binaries like bof_64 as well. I'll try installing 32bit libs anyways.

Thanks again for the help.

Something like https://askubuntu.com/questions/522372/installing-32-bit-libraries-on-ubuntu-14-04-lts-64-bit will help you install 32bit libraries. Also make sure the 64bit ones are marked executable chmod +x challenges/ret
