+# `IoReader::read()`: user-provided `Read` on uninitialized buffer may cause UB
+
+Affected versions of this crate passes an uninitialized buffer to a user-provided `Read` implementation.
+
+Arbitrary `Read` implementations can read from the uninitialized buffer (memory exposure) and also can return incorrect number of bytes written to the buffer.
+Reading from uninitialized memory produces undefined values that can quickly invoke undefined behavior.
+
+The flaw was fixed in commit 599313b by zero-initializing the buffer (via `self.buf.resize(len, 0)`) before passing it to `Read`.
