NMAP crash with ssh-auth-methods.nse (patch included) #1077
When testing ssh-auth-methods.nse against non-standard ports, I forgot to specify ports and NMAP crashed. I have narrowed it down to running the script against port 139. I ran a debug and found the crash appears to be caused by a double free of session data. This appears to be due to a session pointer not being NULLed after the session is freed. Attached is a patch that appears to fix the issue.
