Subject: nmap <= 5.21 is vulnerable to Windows DLL
	Hijacking Vulnerability.

1. Overview
nmap <= 5.21 is vulnerable to Windows DLL Hijacking Vulnerability. 

2. Vulnerability Description
nmap passes insufficiently qualified path for the dll "airpcap.dll" while opening a file using nmap

Timeline
27-08-2010 - Discovered Vulnerability
31-08-2010 - Disclosed at nmap-dev mailing list
04-09-2010 - Response and fix from developers

3. Exploitability
A file extension needs to be registered with nmap to exploit the vulnerability and a crafted file needs to be 
opened from a network share. Currently nmap is not registered with any filename so users are not at risk by default.

6. Impact
Remote Code Execution in context of nmap process.
