The vulnerability is caused due to a boundary error in the AskJeevesToolBar.SettingsPlugin.1 ActiveX control (askBar.dll) when handling the "ShortFormat" property. This can be exploited to cause a stack-based buffer overflow by assigning an overly long (greater than 500 bytes) string to the affected property. Successful exploitation allows execution of arbitrary code. The vulnerability is confirmed in version 4.0.2. Other versions may also be affected. SOLUTION: Set the kill-bit for the affected ActiveX control.
