The PhotoStockPlus Uploader Tool ActiveX control contains several stack buffer overflows, which may allow a remote, unauthenticated attacker to execute arbitrary code on a vulnerable system.
PhotoStockPlus provides an image uploader ActiveX control, which is provided by the file PSPUploader.ocx. This ActiveX control contains stack buffer overflows in multiple initialization parameters, which can allow an overwrite of the process Structured Exception Handler (SEH).
PhotoStockPlus has indicated that the vulnerable ActiveX control is no longer used by the company. However, it is important to realize that any system that has used the control in the past may be at risk.
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.
