Re: [Full-disclosure] The Dangerous of Fakeroot
It actually doesn't matter what OS or what kind of kernel security is on going, this 'hole' of yours does not exist. and why would I want to 'try make program exec /bin/sh 'n setuid it to root' that's just moronic. so in closing, and once again this will NOT work on any Linux OS or Linux Kernel Thanks for all the fish. 3 On Mon, Aug 27, 2012 at 6:52 PM, Teguh i...@egeektronic.com wrote: @ Jeffrey Walton thx for the references @ Wiliam Steck what OS you tested on?
