The CTimeoutEventList::InsertIntoTimeoutList function in Microsoft mshtml.dll uses a certain pointer value as part of producing Timer ID values for the setTimeout and setInterval methods in VBScript and JScript, which allows remote attackers to obtain sensitive information about the heap memory addresses used by an application, as demonstrated by the Internet Explorer 8 application.
