Can you retry with the latest version of Ncrack (0.7 on github) compiled against OpenSSL 1.1?

@ithilgore Problem still exists in Ncrack 0.7 compiled against OpenSSL 1.1

I found a solution, try to save your file without .txt extension that's work for me, have a good day 👍

Had the same issue today wit ncrack 0.5. (This is the version found in the fedora repos.)
I found that the wordlist needs to have a blank line at the end in order not to segfault.

Just compiled ncrack 0.7 with openssl 1.1.0i-fips. Now I can't brute any ssh service anymore.
I tried 4 test cases in total:
- wordlist without extension and without trailing blank line
- wordlist without extension and with trailing blank line
- wordlist with extension and without trailing blank line
- wordlist with extension and with trailing blank line
I attached the dmesg log to this message.

Is there anything new on this? I'm having the same issue.
from ncrack.
just updating ncrack will resolve the issue(apt-get -y install ncrack).
ncrack version 0.6 seems all affected.

Hey @ithilgore ,
This bug still persists on ncrack 0.8. As mentioned on this thread, it does not segfault when the password list has an empty line.
from ncrack.
still segfault:
- using password file without extension
- using password with a empty line
- patch with the pull request #108
seems defferent passwords cause segfault too
ncrack version 0.8
