Grid is a data structure grid for rust. 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.

No affected version ranges are stored yet. Use the vendor advisory before you decide this record does not apply.
