The transpose crate before 0.2.3 for Rust allows an integer overflow via input_width and input_height arguments.

Affected: crates.io: transpose

Given the function `transpose::transpose`: ```rust fn transpose<T: Copy>(input: &[T], output: &mut [T], input_width: usize, input_height: usize) ```

The safety check `input_width * input_height == output.len()` can fail due to `input_width * input_height` overflowing in such a way that it equals `output.len()`. As a result of failing the safety check, memory past the end of `output` is written to. This only occurs in release mode since `*` panics on overflow in debug mode.

Exploiting this issue requires the caller to pass `input_width` and `input_height` arguments such that multiplying them overflows, and the overflown result equals the lengths of input and output slices.
