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.
