temporarily disable ASLR during debugging sessions
root@oco:~$ setarch `uname -m` -R ./27_stack_overflow.out
* this cmd will run the program in the absence of ASLR
* can provide the /bin/bash if not providing the program name
- setarch `uname -m` -R /bin/bash
root@oco:~$ cat /proc/sys/kernel/randomize_va_space
2
* this means the ASLR is active
root@oco:~$ sudo bash -c "echo 0 > /proc/sys/kernel/randomize_va_space"
* some OS doesn't treat the redirection with super user privileges
- sudo echo 0 > /proc/sys/kernel/randomize_va_space
- when this issue is encountered, simply run bash as a super user then proceed w/ the cmd
* the "bash -c" cmd will execute the string inside as a command in a new Bash shell.
root@oco:~$ cat /proc/sys/kernel/randomize_va_space
