Overview

Affected versions of this package are vulnerable to Use of Uninitialized Resource. Arbitrary Read implementations can read from the uninitialized buffer (memory exposure) and also can return an incorrect number of bytes written to the buffer. Reading from uninitialized memory produces undefined values that can quickly invoke undefined behavior.
