详细描述
在INTERNET的Explorer注册向导(regwizc.dll)中存在一个缓冲溢出漏洞,这个控件中被标明为'Safe for Scripting'.可被恶意者利用此控件来执行两进制代码

测试代码
REGWIZC The Registration Wizard control used by Microsoft to register MS products also contains a buffer overrun in the 'InvokeRegWizard' method. When called with a long string, pre-pended with '/i', we can gain control of the RET address and exploit the control in a similar manner as the PDF control. This exploit will cause a 'Regwiz.log' file to be created in the temporary directory, and once again will execute CALC.EXE and terminate the host. ;gtobject classid="clsid:50E5E3D1-C07E-11D0-B9FD- 00A0249F6B00" id="RegWizObj"> ;gt/object>
