Setup: Ubuntu 18×64 x86_64 application Arbitrary code execution from inside the application I’m trying to write code which should be able to find structures in memory even with ASLR enabled. Sadly, I couldn’t find any static references to those regions, so I’m guessing I have to use the bruteforce way and scan the process memory. What I tried to do

Dumpout Process Memory Layout During Loading Time
I am working on a project where I need to use LD_PRELOAD to load some libraries into the memory space. It’s like: Due to certain reasons (I am actually working on some binary hacking), I must know the memory address (not a symbol) of certain functions (let’s say, foo) in libapp.so and instrument the binary code of my_app before execution.
Why aren’t glibc’s function addresses randomized when ASLR is enabled?
In trying to understand ASLR, I built this simple program: ALSR seems to be enabled: and I used GCC to compile the program: Every time I run this program, it prints the same address (0x400450). I would expect this program to print a different address each time if glibc is loaded at a random address. This is surprising to me,
