In mov_read_ispe(), uint32_t width/height values from a crafted HEIF ispe box are stored into signed int fields without bounds checking, allowing values exceeding INT_MAX to become negative. In read_image_grid(), accumulating these values causes signed integer overflow (undefined behavior per C17 section 6.5), which on x86 wraps to a small positive value, bypassing downstream validity checks.</p> <p><strong>Affected:</strong> FFmpeg</p> <p>FFmpeg before 9.0 has a signed integer overflow in libavformat/mov.c.
