you have yet to demonstrate that this bug will allow the system to be compromised - you'll be able to save a file in /var/qmail/queue, then exec it, or a system binary - but you'll still be stuck with very poor privileges.
the program at: http://www.guninski.com/where_do_you_want_billg_to_go_today_4.html#qpopup executes code with root privileges via qmail-popup for me. the same commands zero writing bug. notes for the qmail fanatics: - this is not a dos, this is remote code execution with root privileges - with local access the offsets are easily found, so exploitation is very reliable in this case - djb gives installation instructions in INSTALL which allow root compromise - the payload consists of "int3" which produces trace trap for the microsoft certified solitaire experts (MCSEs) who can't get it -- where do you want bill gates to go today? _______________________________________________ Full-Disclosure - We believe in it.
