rgod has discovered some vulnerabilities in ImagN' for Windows, which can be exploited by malicious people to compromise a user's system.
The vulnerabilities are caused due to boundary errors within the IMW32040.OCX ActiveX control when handling certain properties and methods, e.g. "FileName" property, "BeginReport()", "LoadFox()", "DefineImageFox()", "CopyBufToClipExA()", "CreatePictureExA()", "LoadEx()", "DefineImageEx()", and "DefineImage()" methods. These can be exploited to cause stack-based buffer overflows via overly long arguments passed to the affected properties or methods.
Successful exploitation allows execution of arbitrary code.
The vulnerabilities are confirmed in version 4.00. Other versions may also be affected.
Solution: Set the kill-bit for the affected ActiveX control.
