Error when running Vuzzer using example command

[pratikbhd]

I have setup Vuzzer on a VirtualBox following all the instructions as mentioned in the README. I tried running runfuzzer.py as mentioned in the wikiHOWTO.md file but received the following error:

$ python runfuzzer.py -s '/home/osboxes/vuzzer/vuzzer64/bin/who %s' -i 'datatemp/utmp/' -w 'idafiles/who.pkl' -n idafiles/who.names -o '0x00000000'

Any idea why this might be happening?

Are you using 64bit who binary? I guess you are using who binary from vuzzer repository, which is compiled as 32bit executable.

[pratikbhd]

Yes, I was using the who binary provided in the vuzzer repository. I was under the assumption that they too were ported to 64-bit. I will try running them on the 64-bit who library then. Thanks!

[RKX1209]

Yeah, It's bit confusing. VUzzers who binary comes from 32bit LAVA-M dataset. Previously I tried to create 64 bit version of it by using lava, but it doesn't works well. If you succeed to create 64 bit LAVA-M dataset, it's significant to add these binaries to VUzzer64s repository as bin samples :)

Any news on LAVA-M 64-bit binaries? I'm going crazy trying to run these 32-bit binaries with PIN... :(

Hi @cgr71ii you can download tthe entire LAVA-M dataset from https://sites.google.com/site/steelix2017/home/lava and compile it for 64-bit. it should work well. Unfortunately, I am not able to update the LAVA-M binaries yet (sorry about it), but I am about to do a full overhauling of this repo. it will take time though!!

[cgr71ii]

That's exactly what I've been trying these days :( Fortunately, I've finally succeeded!

My problem was related to libacl.so, since I had no the soft link created, and it is not created in the Ubuntu versions I have tried (16.04, 18.04 and 20.04). After I noticed that this was the problem, I created the soft link:

sudo ln -s /lib/x86_64-linux-gnu/libacl.so.1.1.0 /lib/x86_64-linux-gnu/libacl.so

Once this was done, I just executed validate.sh from each binary folder and I generated the binaries, and they work well with PIN! Just in case you need these binaries, I attach them (they are also available at BOA): LAVA-M_64-bits.tar.gz

Thanks for the help!

This is great. Thank you @cgr71ii And really sorry for responding to this contribution soooo late. I will add these binaries into the repo.
