stb_image is a single file MIT licensed library for processing images.
If stbi__load_gif_main
in stbi_load_gif_from_memory
fails it returns a null pointer and may keep the z
variable uninitialized. In case 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. This may result in a program crash.
