Derek Callaway has reported a security issue in ThinkVantage System Update, which can be exploited by malicious people to conduct spoofing attacks.
The problem is that the application does not perform SSL certificate chain verification when connecting to the update server.
Successful exploitation allows e.g. downloading and executing malicious programs, but requires that the application connects to a malicious update server providing a specially crafted X.509 certificate (e.g. via DNS poisoning).
The security issue is reported in version 3.13.0005. Other versions may also be affected.
