DISCLAIMER FOR SECURITY RESEARCH SOFTWARE

This software is provided for authorized security research, education, and
defensive testing only. By using this software, you agree that:

1. You will only run the exploit modes (--exploit-*) on systems you own or
   are explicitly authorized to test.
2. You understand that the exploit modes modify the kernel page cache copy
   of /etc/passwd and that this is a privilege-escalation operation while
   it persists. The on-disk file is not modified.
3. The authors disclaim all liability for any misuse of this software.
