Exception while connection on Fedora 39 - Python 3.12

[Exiled1]

Versions:

• GDB: 13.2
• Pwndbg: 2023.07.17 build: e230a85
• GEF: GEF: rev:951872bd965d8748ae94c75c619e396fbfc8e01b (Git - clean)
• Binary Ninja: 3.5.4526 Personal Challenge: (Death Note) https://pwnable.tw/challenge/#10
• Environment: Kali virtual machine

Potentially strange environment configurations: I am currently using this script to be able to swap between gdb versions

• https://github.com/apogiatzis/gdb-peda-pwndbg-gef

Behavior: After setting up the RPC server to localhost with the default port,

And after confirming that there was a listening service on 127.0.0.1:

I use the command gdb-pwndbg ./death_note (Should be the same thing as gdb with pwndbg installed), and use the following commands:

• b main
• entry
• decompiler connect binja --host 127.0.0.1 --port 3662 To which I receive the response"
• Python Exception <class 'TypeError'>: expected string or bytes-like object, got 'list' Error occurred in Python: expected string or bytes-like object, got 'list'

The same error occurs when I use GEF, and GDB, GEF:

GDB:

If you would like me to modify my environment to troubleshoot, I absolutely can :).

Hi @Exiled1, would you be able to provide your Python version? Using this binary on Ubuntu 22.04, which has Python 3.10, I was unable to reproduce this bug :(. My best guess is you have a rather old Python version that changed how one of the library calls work

Hello! I actually have Python 3.11.7 installed on this machine, would that be a problem?

So it turns out this was fixed in https://github.com/mahaloz/decomp2dbg/commit/60822010a98e69c338211f928f2270960fc5a313, but the Python pip remote was not updated... ha! However, we also fixed it by installing binutils gcc. Should this bug reappear, it's due to those not being installed.
