Ubuntu关闭地址空间随机化(ASLR)的方法

确认ASLR是否已经被打开，"2"表示已经打开

shanks@shanks-ubuntu:/home/shanks# cat /proc/sys/kernel/randomize_va_space 2

切换到root用户来做更新，直接使用sudo会出现下面结果

shanks@shanks-ubuntu:~$ sudo echo 0 > /proc/sys/kernel/randomize_va_space bash: /proc/sys/kernel/randomize_va_space: Permission denied

要确认root已经被解锁，否则是切换不到root下的

shanks@shanks-ubuntu:~$ suPassword: su: Authentication failure

解锁root，可采用以下方式

shanks@shanks-ubuntu:~$ sudo passwdEnter new UNIX password: Retype new UNIX password: passwd: password updated successfully

切换至root下关闭ASLR

shanks@shanks-ubuntu:~$ suPassword: root@shanks-ubuntu:/home/shanks# echo 0 > /proc/sys/kernel/randomize_va_space root@shanks-ubuntu:/home/shanks# cat /proc/sys/kernel/randomize_va_space 0
