Gabriel Menezes Nunes has discovered a security issue in aMSN, which can be exploited by malicious people to conduct spoofing attacks.
The security issue is caused due to the application improperly verifying the validity of the SSL certificate presented when logging in. This can be exploited to spoof a valid server and obtain the user's MSN username and password via e.g. a man-in-the-middle attack.
The security issue is confirmed in version 0.97.2. Other versions may also be affected.
Solution: Do not rely on the security provided by SSL when using aMSN.
