是否有某种在Android ASLR保护？ [英] Is there some sort of ASLR protection on Android?

问题描述

我想知道，如果有人可以访问与函数地址库，这将是相同的，从程序的一个实例到另一个？

I want to know if someone could access libraries with function addresses that would be the same from one instance of the program to the other?

推荐答案

地址空间布局将是pretty的从运行相一致的同一台设备上运行。许多主要的系统库是由受精卵ploaded $ P $，所以继承为共享映射的儿童它叉掉分化成应用程序。我猜想他们重新映射在虚拟内存中的水平是可能的，但会产生一种动力，重新连接处罚，将是相当棘手的执行。

The address space layout will be pretty consistent from run to run on the same device. A lot of the major system libraries are preloaded by zygote, and so inherited as shared mappings by the children it forks off to differentiate into applications. I suppose remapping them at the virtual memory level would be possible, but would incur a sort of dynamic-re-linking penalty and would be fairly tricky to implement.
