WS-2021-0027
Good to know:
Date: February 17, 2021
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.
