    Summary: Tape::take_bytes exposes uninitialized memory to a user-provided Read

    Details: Affected versions of this crate passed an unininitialized buffer to a user-provided `Read` instance in `Tape::take_bytes`. This can result in safe `Read` implementations reading from the uninitialized buffer leading to undefined behavior. The flaw was corrected in commit `1f2dc7f37dd` by removing the unsafe block and zero-initializing the buffer.
