This is to improve my PWN toolbox for CTF.
Sometimes I get an executable file with included libc.so.6 and ld-linux-x86-64.so.2. Supposed to run in a docker container.

But it would be nicer to run gdb etc on my host machine. The problem with the current .exe is, that if I am in the directory with the libraries, then I can’t even run ls – As ls has issues with the included libraries.

Is there any way I can run gdb with os libs – and launch the executable in a different directory – setting the current directory for that exe -and thus have that exe use the shared libraries in its home directory?

I can’t find .anywhere in /etc/ld.so.conf.d/*

And can gdb use one set of libraries, and the app another? Or is this impossible? It seems like gdb runs executables in its own address space and GOT.

I can run the file in Docker. Things are pretty bad if I have exe and libs in same dir – disturbs my bash – even ls does not work. exe will not run without the included libs.
If I move libs to ./libs and cd ./libs; ../chall then the application will run interactive. Thus it can run in its own context.

But I want gdb to control it.

I tried set env LD_LIBRARY_PATH /mnt/c/Users/xyz/Downloads/metaforge/libs` before run inside `gdb. Segfaults, so does not work.
