Secunia integrated with Microsoft WSUS

Description:
A vulnerability has been discovered in Microsoft Windows, which can be exploited by malicious people to compromise a vulnerable system.

The vulnerability is caused due to a boundary error in the HTML Help ActiveX control (hhctrl.ocx) when handling the "Image" property. This can be exploited to cause a buffer overflow by setting an overly long string multiple times for the property.

Successful exploitation allows execution of arbitrary code.
