it doesnt contribute to testing, i can assure you there's been enough
'tests' of this exploit.

Actually Ryan, I'll think you'll find a lot of people just wanted to
contribute towards testing, as most authors will appreciate the masses
testing on as many systems as possible.

It's not a case of anyone "showing off", it's simply that a lot of people
simply don't have time to read the "small print".

Hey Dan,

Freaking THANK YOU first and foremost. I've been waiting for someone to
say that for days now, and was just about to myself.

Just because everyone and their brother want's to show off that they can
compile & run some software (herp a derp, good job) DOESN'T mean they should
immediately post it here. I tested it against an OLDER KERNEL on purpose
because I actually read the headers and the exploit worked as expected. I
knew that this was responsibly disclosed, so it was already patched on any
system that I updated. If you don't have the proper symbols, then the
exploit doesn't have the proper offsets, and the exploit will fail. Plain
and simple. *THEN* there's people who don't even bother to read that "Red
Hat does not support Econet by default". DOES NOT. As in the exploit WON'T
WORK!

It's pathetic that the original exploit dev has to waste his time saying
the same thing 5 times.

Please don't inundate me with e-mail because none of you bothered to read
the exploit header.

The exploit so far has a 100% success rate on the systems it was designed
to work on.

I don't think this is rocket science.  If your distribution does not
compile Econet, then the exploit obviously won't be able to open an Econet
socket.  This includes Arch Linux, Gentoo, Fedora, Red Hat, CentOS,
Slackware, and more.  This doesn't mean you're not vulnerable, it just means
this particular exploit won't work.

If your distro doesn't export the relevant symbols (Debian), ditto above.

If your distro has patched the Econet vulnerabilities I used to trigger
this (Ubuntu), ditto above.

This was done on purpose, to avoid giving a weaponized exploit to people
who shouldn't have one.
