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 _______________________________________________ Full-Disclosure - We believe in it.
