Description:
rgod has discovered a vulnerability in 4XEM VatDecoder, which can be exploited by malicious people to compromise a user's system.
The vulnerability is caused due to a boundary error in the VATDecoder.VatCtrl.1 ActiveX control (VATDecoder.dll) when handling strings assigned to the "Url" property. This can be exploited to cause a stack-based buffer overflow by assigning an overly long string to the affected property.
Successful exploitation allows execution of arbitrary code.
The vulnerability is confirmed in VATDecoder.dll version 1.0.0.27 and reported in version 1.0.0.51. Other versions may also be affected.
Solution:
Set the kill-bit for the affected ActiveX control.
