3) Description of Vulnerability

Secunia Research has discovered two vulnerabilities in various 
Symantec products, which can be exploited by malicious people to 
compromise a user's system.

The vulnerabilities are caused due to errors in the AxSysListView32 
and AxSysListView32OAA ActiveX controls (NavComUI.dll) when handling 
the "AnomalyList" and "Anomaly" properties respectively as they take 
a VARIANT* as argument.

Successful exploitation allows execution of arbitrary code.
