Impact:

System access

Solution Status:

Unpatched

CVE Reference(s):

Description


A vulnerability has been discovered in Creative Software AutoUpdate Engine ActiveX Control, which can be exploited by malicious people to compromise a user's system.

The vulnerability is caused due to a boundary error within the Creative Software AutoUpdate Engine ActiveX control (CTSUEng.ocx) when handling the "CacheFolder" property. This can be exploited to cause a stack-based buffer overflow when a user is tricked into visiting a malicious website.

Successful exploitation allows execution of arbitrary code.

The vulnerability is confirmed in versions 1.51.1.0 and 2.0.12.0. Other versions may also be affected.


Solution:
Set the kill-bit for the affected ActiveX control.

What you have done isn't what Secunia would define as a solution. That would be an update to the product which fixes the vulnerability. What you have is a workaround that has set a killbit for the ActiveX in the registry which prevents it from executing. Secunia works by examining the executable files for a product to determine the version installed. There is no way it can detect what you have done. Since the vulnerability can no longer be exploited, you can safely click Ignore so that you do not keep getting alerted to this.

I'm not going to comment on Creative Lab's attitude to their customers if they can't be bothered to fix this.

If this is showing as vulnerable just use this method to remove it then complete a full PSI rescan & U should be OK. It will not affect the workings of Windows.
