OpenSSL VS GLFW

Today, April 7th, 2024, marks the 10-year anniversary since CVE-2014-0160 was published. This security vulnerability known as "Heartbleed" was a flaw in the OpenSSL cryptography software, the most popular option to implement Transport Layer Security (TLS). In more layman's terms, if you type https:// in your browser address bar, chances are high that you are interacting with OpenSSL.

At this point I pretty much understand the entire process on how the xz backdoor came to be: its execution stages, extraction from binary "test" files etc. But one thing puzzles me: how can the ifunc mechanism be used to replace something like RSA_public_decrypt? Granted this probably stems from my lack of understanding of ifunc, but I was under the impression that in order for the ifunc mechanism to work in your code, you have to explicitly mark specific function with multiple implementations with __attribute__ ((ifunc ("the_resolver_function"))). Looking at the source code of the RSA function in question, ifunc attribute isn't present:

https://github.com/openssl/openssl/blob/master/crypto/rsa/rsa_crpt.c#L51

So how does the backdoor actually replace the call? Does this means that the ifunc mechanism can be used to override pretty much anything on the system?

OpenSSL and Go crypt/tls has no support yet, so none of the webservers that depend on them support it. Apache, Nginx, and Caddy, they all need upstream ECH support first.

- https://github.com/openssl/openssl/issues/7482

- https://github.com/openssl/openssl/pull/22938

- https://github.com/golang/go/issues/63369

If I'm understanding the draft correctly, I think the webserver you're hosting your sites on would need it implemented as it requires private keys and ECH configuration. In the example of nginx since it uses openssl, openssl would need to implement it. I found an issue on their Github but it's still open: https://github.com/openssl/openssl/issues/7482

I confirmed that the systm was on 1.1.1f with openssl version command. Hmm...... I check the openssl version in the repo with apt list... LOL package names wernt helpful. finally went to the repo pages and found that its still on 1.1.1f, https://launchpad.net/ubuntu/+source/openssl. Meenwhile I looked up the version history on https://www.openssl.org/ and saw that 1.1.1v was released at the beginning of this month... ok. I can understand it it was out less then 30 days. I looked up when f came out, end of MARCH 2020. NEARLY 3-1/2 YEARS

Minecraft runs on various Javas.

And there's a known issue with an interaction between minecraft, Java, and the video drivers that crashes out and it can be traced back all the way to here: https://github.com/glfw/glfw/issues/1997

It's not fixed.

Window context manager - glfw, sdl

Types of tools for creating a gui (and how those tools approximately work): 1. Utilize the native _graphical interface API_, and depending on the platform, they have specific layers to interface: * Wayland, X11, for Linux * [GDI](https://learn.microsoft.com/en-us/windows/win32/gdi/windows-gdi) for windows * [Quartz](https://en.wikipedia.org/wiki/Quartz\_(graphics\_layer)) for macOS Example - GTK uses [wayland](https://gitlab.gnome.org/GNOME/gtk/-/blob/main/docs/reference/gdk/wayland.md) ([source code](https://gitlab.gnome.org/GNOME/gtk/-/tree/main/gdk/win32)) [X11](https://gitlab.gnome.org/GNOME/gtk/-/blob/main/docs/reference/gdk/x11.md) ([source code](https://gitlab.gnome.org/GNOME/gtk/-/tree/main/gdk/x11)) GDI ([source code](https://gitlab.gnome.org/GNOME/gtk/-/tree/main/gdk/win32)) Quartz ([source code](https://gitlab.gnome.org/GNOME/gtk/-/tree/main/gdk/macos)) [How to use wayland display server](https://bugaevc.gitbooks.io/writing-wayland-clients/content/black-square/the-wayland-client-library.html) (TODO missing "animation" section) 2. Utilize opengl _or other low level graphics api's_ with window context, use GPU to render widgets * Window context manager - [glfw](https://github.com/glfw/glfw), [sdl](https://www.libsdl.org/) * contexts and surfaces, reading input, handling events Example: ImGui, NanoVG, Nuklear, raylib Why? Mainly used for game development, but also good for gui's. _(i haven't seen any examples that uses this method that are used for developing general-use graphical user interfaces.)_

GLFW: A library for window creation and managing user input.

Not SDL2, but GLFW has something like that under the tests/ directory:

https://github.com/glfw/glfw/blob/master/tests/triangle-vulk...

I'm not familiar with LWJGL, my 5 seconds on their website makes me think you might be looking for something like GLFW https://www.glfw.org/ to handle I/O and window creation/management.

Consider GLFW3 for windowing and GLAD for function loading. I've used this combination myself successfully. Granted, that is "two things" you need, but OTOH it'll work well.

There is a pattern to it which is usable with every GitHub repository. For example, GLFW v3.3.8 can be fetched from: https://github.com/glfw/glfw/archive/refs/tags/3.3.8.tar.gz

That is a static or import library for glfw. You need add the path to the directory where this file is located to the "library directories", see: https://www.learncpp.com/cpp-tutorial/a2-using-libraries-with-visual-studio-2005-express/
