TITLE:
aMSN SSL Certificate Validation Security Issue
SECUNIA ADVISORY ID:
SA35621
VERIFY ADVISORY:
http://secunia.com/advisories/35621/
DESCRIPTION:
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.
PROVIDED AND/OR DISCOVERED BY:
