Hello, attached 0day kernel 2.6 local root exploit. This is a new genuine bug, unpatched in 2.6.17.4 - don't get confused by prctl inside - it is only used to change process status.
Tested on dan@n-box ~ $ uname -a Linux n-box 2.6.16-gentoo-r9 #1 Fri Jun 9 16:44:22 CEST 2006 i686 Intel(R) Pentium(R) M processor 2.00GHz GNU/Linux dan@n-box ~ $ ./h00lyshit ./Media/Audio/DnB/TheEngineer_060331.mp3 preparing trying to exploit ./Media/Audio/DnB/TheEngineer_060331.mp3 sh-3.1# id uid=0(root) gid=100(users) groups=7(lp),10(wheel),18(audio),27(video),35(games),81(apache),100(users),7353(svnusers) sh-3.1# whoami root sh-3.1#
The code exploits a root race in /proc
So it does :)
have a nice day.
But this means that I've gotta worry about more servers now! Dam it! And is there a workaround to protect against this attack?
