Who is Vulnerable?
Vulnerability Description	Symantec products include various software applications that deal with security and information management. A remote attacker could exploit this issue by convincing a user to visit a specially crafted HTML document or open a malicious web page. Successful exploitation could result in remote code execution on the target system once the malicious page is loaded. The vulnerabilities are due to errors in AxSysListView32 and AxSysListView32OAA (NavComUI.dll) ActiveX controls that fail to properly handle "AnomalyList" and "Anomaly" properties.
