Re: [Full-disclosure] Linux kernel exploit

[Ryan Sears <rdsears@xxxxxxx>]

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.
