One reason that you might need to parse ELF files is when trying. Normally the details of ELF files are invisible to developers, but certain tasks can call for one to peer into their inscrutable depths. Most Unix systems, including Linux, use the ELF format for executables and object files. While this is not necessarily the most practical solution and not possible if you don't trust the executable, it is fun and it does the ultimate check that we really care about, which is if the Linux kernel / dynamic loader changes the executable location or not. A crash course in modern hacking techniques, Ethical Hacking is already being used to prepare the next generation of offensive security experts. The Curious Case of Position Independent Executables.

I have explained how to do that in detail at: One very direct thing that you can do is to run the executable twice through GDB and see if the address changes across runs due to ASLR.

Before that it just printed shared object for PIE. When you launch setup.exe a number of pre-requisite software are installed on your system. It looks like stack is not position independent If you really want to continue, because you think retrowrite has made a mistake, pass -ignore-no-pie. The feature was introduced in 5.33 but it did just a simple chmod +x check. In case you load a non position independent code you will get the following message: (retro) retrowrite stack stack.c RetroWrite requires a position-independent executable. For example, a PIE executable shows as: main.out: ELF 64-bit LSB pie executable, x86-64, version 1 (SYSV), dynamically linked, not strippedĪnd a non-PIE one as: main.out: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), statically linked, not stripped File 5.36 actually prints it clearly if the executable is PIE or not. Wl,-z,execstack is needed on todays Linux systems to force executable data.-no-pie is needed on some Linux systems to disable position independent executable (otcc relies on the fact that the C allocated data is at an address < 0x80000000.
