Summary

Details

stb_image is a single file MIT licensed library for processing images. A crafted image file may trigger out of bounds memcpy read in stbi__gif_load_next. This happens because two_back points to a memory address lower than the start of the buffer out. This issue may be used to leak internal memory allocation information.
