Extended Description

Microsoft Windows is prone to a vulnerability that may allow remote attackers to execute code through the Windows Shell. The cause of the vulnerability is related to how the operating system handles unregistered file types. The specific issue is that files with an unknown extension may be opened with the application specified in the embedded CLSID. The victim of the attack would be required to open a malicious file, possibly hosted on a Web site or sent through email. Social engineering would generally be required to entice the victim into opening the file.
