CVE-2023-45662
Description
stb_image is a single file MIT licensed library for processing images. When stbi_set_flip_vertically_on_load is set to TRUE and req_comp is set to a number that doesn’t match the real number of components per pixel, the library attempts to flip the image vertically. A crafted image file can trigger memcpy out-of-bounds read because bytes_per_pixel used to calculate bytes_per_row doesn’t match the real image array dimensions.
