Descriptions

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.

stb_image es una librería con licencia MIT de un solo archivo para procesar imágenes. Cuando `stbi_set_flip_vertically_on_load` se establece en `TRUE` y `req_comp` se establece en un número que no coincide con el número real de componentes por píxel, la librería intenta voltear la imagen verticalmente. Un archivo de imagen manipulado puede provocar una lectura fuera de límites de `memcpy` porque los `bytes_per_pixel` utilizados para calcular `bytes_per_row` no coinciden con las dimensiones reales de la matriz de imágenes.
