From version 0.17.0 to before version 1.0.1, an integer overflow in Grid::expand_rows() can corrupt the relationship between the grid’s logical dimensions and its backing storage. After the internal invariant is broken, the safe API get() may invoke get_unchecked() with an invalid index, resulting in Undefined Behavior. This issue has been patched in version 1.0.1."

Desde la versión 0.17.0 hasta antes de la versión 1.0.1, un desbordamiento de entero en Grid::expand_rows() puede corromper la relación entre las dimensiones lógicas de la cuadrícula y su almacenamiento de respaldo. Después de que el invariante interno se rompe, la API segura get() puede invocar get_unchecked() con un índice inválido, lo que resulta en Comportamiento Indefinido. Este problema ha sido parcheado en la versión 1.0.1."
