# 鬼仔注：相关日志 Linux爆本地提权漏洞 请立即更新udev程序 、 udev,linux有史以来最危险的本地安全漏洞

# milw0rm.com [2009-04-20]

#!/bin/sh
# Linux 2.6
# bug found by Sebastian Krahmer
#
# lame sploit using LD technique
# by kcope in 2009
# tested on debian-etch,ubuntu,gentoo
# do a 'cat /proc/net/netlink'
# and set the first arg to this
# script to the pid of the netlink socket
# (the pid is udevd_pid - 1 most of the time)
# + sploit has to be UNIX formatted text :)
# + if it doesn't work the 1st time try more often
#
# WARNING: maybe needs some FIXUP to work flawlessly
## greetz fly out to alex,andi,adize,wY!,revo,j! and the gang
