Stack Overflows - Defeating Canaries, ASLR, DEP, NX
is there anyway to disable ASLR in Linux kernel 2.6.32-71.el6.x86_64, with Apache privileges?? I tried this commands:
sudo bash -c "echo 0 > /proc/sys/kernel/randomize_va_space"
but because i do not have normal user privilege, this command did not work. Someone wrote exploit to get root access, but this exploit gives the following error message: "[11754: 5 (255)] tcsetattr: Invalid argument". I asked him about this and he told me to disable NX and ASLR.
I am working with centOS Lnux, Kernel 2.6.32-71.el6.x86_64, and there are many packages installed on the system like : mailman 2.1.12-14.e16, mailscanner 4.83.5-1, postfix 2.6.6-2.316.x86-64, dovecot 2.0-0.10.beta6.20100630.e16.x86-64, crontabs 1-10-32.1.e16, mysql 5.3-3
I also have a mysql account - I tried to add user to linux via mysql command line, but it did not work. Is there any way to create a linux user via mysql command line?
