You can suggest it. However, ftp.exe is also linked with the secure
exception handlers option. How do you divert execution when ftp.exe is
running on a platform with encrypted global pointers? ftp.exe is no
Internet Explorer, either, you cannot arbitrarily load third party DLLs
in it. Why, it doesn't even link shell32.dll or ole32.dll. And I remind
you these are buffer overflows in a text field of an user interface

Rajesh and others like him have been peddling this "vulnerability" for
months if not years. Some security "professionals" should stop fooling
themselves and have the basic honesty to admit their behavior is rather
more fitting of a small-time loan shark or mafia picciotto, if not the
honesty to submit straight away to the vendor what is clearly just a bug
with no strategical security implications
