Microsoft Internet Explorer 4.1/5.0 for Windows 95/Windows NT 4,Windows 98 Registration Wizard Buffer Overflow Vulnerability
source: https://www.securityfocus.com/bid/671/info
There is a buffer overflow in the Internet Explorer Registration Wizard control (regwizc.dll). This control is marked 'Safe for Scripting' . Arbitrary commands may be executed if the control is run in a malicious manner.
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.
