Remote DoS with Nmap in Windows XP #459

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
Openhardwaremonitor crashes when using Nmap to scan the TCP-port web-service 
OHM is listening in Windows XP SP3. This doesn't work in Windows 7.

Using Nmap 6.25 with -P0 -sV and OHM 0.5.1 Beta.

This is the output:

"""

Screenshot of the error situation attached. After the error-message OWM exits. 
I can give you PoC in Python if needed.
