Address space layout randomization【ASLR】是避免缓冲区溢出的技术,通过对栈、同享库映射等线性区筹划的随机化,避免攻击者定位攻击代码位置,到达禁止溢出攻击的目的.据研究表明ASLR可以有效的降低缓冲区溢出攻击的成功率,目前Linux、FreeBSD、Windows等主流操作系统都已采取了该技术.

Title: Linux/ARM - Disable ASLR Security - 102 bytes
Date: 2010-06-20
Tested: Linux ARM9 2.6.28-6-versatile

Description:
============
Address space layout randomization (ASLR) is a computer security technique
which involves randomly arranging the positions of key data areas, usually
including the base of the executable and position of libraries, heap, and
stack, in a process's address space.
This shellcode disables the ASLR on linux/ARM
