Overview

Affected versions of this package are vulnerable to Improper Enforcement of Message Integrity During Transmission in a Communication Channel due to improperly caching plaintext state across the STARTTLS encryption boundary. An attacker can inject a plaintext NBD_OPT_STRUCTURED_REPLY before proxying everything else a client sends to the server, potentially leading the client to terminate the NBD session.
