Adobe released an article at their knowledge base regarding this issue.

# Socket connection timing can reveal information about network  
configuration
   http://kb.adobe.com/selfservice/viewContent.do?externalId=kb402956

The fix is to disable socket functionality for Flash Players version  
= 9.0.115 by configuration.


Take care,

# Summary
Due to a design flaw in ActionScript 3 socket handling, compiled  
Flash movies are able to scan for open TCP ports on any host  
reachable from the host running the SWF, bypassing the Flash Player  
Security Sandbox Model and without the need to rebind DNS.
