+# Tape::take_bytes exposes uninitialized memory to a user-provided Read
+
+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.
