I'm offering $100, payable in cash or Bitcoin, for security vulnerabilities. This is primarily for remote vulnerabilities, such as the ability of a target to buffer-overflow the scanner, or even cause it to crash.

But I'd consider other vulnerabilities as well. Does Kali ship this with suid and there's a preload bug? That's not really a vuln in this code, but if it's something I could fix, I'd consider paying a bounty for it.

If you've got a vuln, just announce it. Please send info to the contact above as well, please.

I'll probably get around to fixing it within a month or so. This really isn't heavily used software, so I'm lax on this.

The primary threat is from hostile targets on the Internet sending back responses in order to:

• exploit a buffer-overflow vulnerability
• spoof packets trying to give fraudulent scan results (mitigated with our SYN cookies)
• flood packets trying to overload bandwidth/storage
• bad data, such as corrupting banners or DNS names trying to exploit downstream consumers with bad html or script tags.

The secondary threat is from use of the program. For example, when a bad parameter is entered on the command-line, the program spits it back out in a helpful error message. This is fine for a command-line program that should run as root anyway, but if somebody tries to make it into a scriptable service, this becomes a potential vulnerability.

Unsafe functions like strcpy() are banned.

The code contains an automated regression test by running with the --regress option. However, currently the regression only tests a small percentage of the code.
