Assume that you have an application that runs at System integrity level or High integrity level instead of Medium integrity level, and starts listening to the clipboard events on a computer that is running Windows 7 or Windows Server 2008 R2. You move the same file three times consecutively to the Clipboard by using the Cut command under the right-click menu in Windows Explorer. In this situation, at the third Cut operation, Windows Explorer crashes.
This issue occurs because a stack overflow occurs in Windows Explorer that runs at Medium integrity level.
