CVE reference:	CVE-2003-0665

Description: A vulnerability has been identified in Microsoft Access Snapshot Viewer ActiveX control potentially allowing malicious HTML documents and Microsoft Access Snapshot files to cause a buffer overflow. The problem is that Microsoft Access Snapshot Viewer doesn't verify certain parameters properly. This allows malicous people to create snapshot files, which may cause a buffer overflow and execute arbitrary code. Since the vulnerability exists in a digitally signed ActiveX control this also affects any Internet Explorer, which allows execution of ActiveX. Any site or person may re-introduce this vulnerability until the next update for Internet Explorer, which will set the kill-bit on the vulnerable ActiveX component. Solution: Secunia recommends that you disallow ActiveX for all sites and then only allow ActiveX on a "per site" basis.
