Windows 2000/NT/XP 16-bit Application Permission Bypass Vulnerability

A vulnerability has been reported in Microsoft Windows NT/2000/XP that allows 16-bit applications to bypass execution rights verification.

When a 16-bit application is executed from an already running 16-bit program, it will bypass permission verification, normally done by a program loader. This will result in unauthorized programs being executed.
