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.
