I'm new to Linux operating system.
Last day, I practice "heap exploitation", and they give me an ELF file, and a
libc.so.6 file, and they said I must debug/exploit with that libc file, but I don't know how to use it.
I try to run the ELF file, and I receive "Illegal instruction (core dumped)". After googling, I try with
LD_LIBRARY_PATH but no luck. I'm using LUbuntu 18.04.
So can you guys help me with this case?
