Re: Linux kernel exploit

[Ryan Sears <rdsears () mtu edu>]

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.
