This is currently only qmail on AMD64 with > 4GB of virtual memory, but
people should upgrade anyway.

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?
