Description: "An integer overflow issue exists in Godot Engine up to v3.2 that can be triggered when loading specially crafted.TGA image files. The vulnerability exists in ImageLoaderTGA::load_image() function at line: const size_t buffer_size = (tga_header.image_width * tga_header.image_height) * pixel_size; The bug leads to Dynamic stack buffer overflow. Depending on the context of the application, attack vector can be local or remote, and can lead to code execution and/or system crash." See https://github.com/godotengine/godot/pull/45702. Note that as we don't do GLSAs for GURU, you are fine to close this bug once bumped/patched & cleaned up.
