There is no fixed version for nothings/stb.

Overview

Affected versions of this package are vulnerable to NULL Pointer Dereference when the stbi__load_gif_main in stbi_load_gif_from_memory fails, it returns a null pointer and may leave the z variable uninitialized. If the caller also sets the flip vertically flag, it continues and calls stbi__vertical_flip_slices with the null pointer result value and the uninitialized z value. An attacker can cause a program crash by exploiting this flaw.
