libelfmaster is a C library for loading and parsing ELF objects of any type. The goal of this project was to create an API that is innovative in its ability to be user-friendly, secure, and provide a variety of creative and useful ways to access an ELF object.
Not only that, but this library was largley created for designing reverse engineering applications.
This library is capable of loading binaries with corrupted section headers and it will forensically reconstruct section headers and symbol tables using state-of-the-art techniques, such as PT_GNU_EH_FRAME reconstruction for .symtab functions.
This library is also capable of seamlessly loading both 32bit and 64bit ELF objects, vs. having to compile two seperate libs for each architecture.
The downfall obviously being that this won’t compile on 32bit machines. I am now a guide on this project, as I put it into the hands of the security and reverse engineering community.
I am currently using it to build which is advancing the state of Linux/UNIX binary forensics and HIDS. As I build Arcana, more edge cases come up.
Work in progress. Not fully fuzzed or tested. Needs adept ELF hackers and reverse engineers with a strong C skills.
Has undergone several iterations of fuzzing done with AFL. Currently I am fixing and patching the code and a new alpha release tag will be committed pushed soon (By mid October 2018) Thank you to all who have contributed their fuzzing efforts.
I will create a proper area to name those who should be listed as contributors (Perhaps an Authors file).
NetBSD coding style, submit a PR for review.
The best documentation is to read the code in libelfmaster/examples. elfparse.c is a simple version of readelf, but does not utilize every API function so make sure to look at all examples. This API needs someone to document it.
