Overview
Affected versions of this package are vulnerable to Inadequate Encryption Strength when a server responds to a ClientHello containing psk_dhe_ke without a key_share extension. An attacker can compromise the confidentiality of communications by causing a client to establish a connection without perfect forward secrecy when reusing an authenticated pre-shared key, if the server omits the required key_share extension in its response.
