      "value": "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."

Un archivo de imagen manipulado puede provocar una lectura de memcpy fuera de l\u00edmites en `stbi__gif_load_next`. Esto sucede porque two_back apunta a una direcci\u00f3n de memoria inferior al inicio del b\u00fafer de salida. Este problema puede utilizarse para filtrar informaci\u00f3n de asignaci\u00f3n de memoria interna."
