US-CERT has seen reports of a vulnerability in Macrovision InstallShield. This vulnerability is due to an error in the One-Click Install ActiveX control for InstallScript projects. This ActiveX control is used for loading DLL files. If a user visits a specially crafted website, a maliciously crafted DLL file may be loaded onto the user's system, allowing an attacker to execute arbitrary code.

US-CERT encourages users to do the following to help mitigate the risks:

Review Macrovision Knowledge Base article Q113640 and apply the appropriate hotfix.
Set the kill bit for CLSID {53D40FAA-4E21-459f-AA87-E4D97FC3245A}.
