[Julião Barbin <juliobarbin () hotmail com>]

Good evening friends,
on my pc found the flaw Messenger ActiveX Control Buffer Overflow YVerInfo.dll then entered the site and searched the 
metasploit failure CVE-2007-4515, if the typed commands as the link 
http://www.metasploit.com/modules/exploit/windows/browser/yahoomessenger_fvcom
and ran the command exploit ... there was
[*] Exploit running the background job

[-] Handler failed to bind to 10.20.4.63:4444 (where the machine is vulnerable)
[*] Started reverse handler on 0.0.0.0:4444
[*] Unsing URL: http://0.0.0.0:8080/S85gRUvyp0
[*] Local IP: http://10.20.6.126:8080 / S85gRUvyp0
[*] Server Started.

I wonder why I could not access this vulnerability?

Thanks,
