The Zoomify Viewer ActiveX control contains multiple stack buffer overflows, which can allow a remote, unauthenticated attacker to execute arbitrary code on a vulnerable system.
Zoomify provides software to incorporate zoomable images into web sites. One of the Zoomify products is an ActiveX control for use with Internet Explorer web browsers. The Zoomify Viewer ActiveX control, which is provided by ZActiveX.dll, contains multiple stack buffer overflows.
By convincing a user to view a specially crafted HTML document (e.g., a web page or an HTML email message or attachment), an attacker may be able to execute arbitrary code with the privileges of the user. The attacker could also cause Internet Explorer (or the program using the WebBrowser control) to crash.
We are currently unaware of a practical solution to this problem. Please consider the following workarounds
Disable the Zoomify Viewer ActiveX control in Internet Explorer
