DIP: Dialup IP Protocol Driver version 3.3.7p-uri (25 Dec 96) Written by Fred N. van Kempen, MicroWalt Corporation. I considered this as a sort of old version and did some searching and found something on insecure.org as well as on securityfocus.com. Description: Standard overflow (in the -l option processing). Author: Goran Gajic <ggajic () AFRODITA RCUB BG AC YU> Compromise: root (local) Vulnerable Systems: Slackware Linux 3.4, presumably any other system using dip-3.3.7o or earlier suid root. Date: 5 May 1998 Referring to a bugtraq post from may 5. 1998 I did son research: root@faust:/home/hegi > gdb /usr/sbin/dip
^...... erm, you already have root here notice that 1st ls showed root.dialout, and the rest of the world has only read. so if you're not in the dialout group you cannot exec it. -- teodor
