	    <p> An erlang TLS server configured with cipher suites
	    using rsa key exchange, may be vulnerable to an Adaptive
	    Chosen Ciphertext attack (AKA Bleichenbacher attack)
	    against RSA, which when exploited, may result in
	    plaintext recovery of encrypted messages and/or a
	    Man-in-the-middle (MiTM) attack, despite the attacker not
	    having gained access to the server’s private key
	    itself. <url
	    href="https://nvd.nist.gov/vuln/detail/CVE-2017-1000385">CVE-2017-1000385</url>
	    </p> <p> Exploiting this vulnerability to perform
	    plaintext recovery of encrypted messages will, in most
	    practical cases, allow an attacker to read the plaintext
	    only after the session has completed. Only TLS sessions
	    established using RSA key exchange are vulnerable to this
	    attack. </p> <p> Exploiting this vulnerability to conduct
	    a MiTM attack requires the attacker to complete the
	    initial attack, which may require thousands of server
	    requests, during the handshake phase of the targeted
	    session within the window of the configured handshake
	    timeout. This attack may be conducted against any TLS
	    session using RSA signatures, but only if cipher suites
	    using RSA key exchange are also enabled on the server.
	    The limited window of opportunity, limitations in
	    bandwidth, and latency make this attack significantly
	    more difficult to execute. </p> <p> RSA key exchange is
	    enabled by default although least prioritized if server
	    order is honored. For such a cipher suite to be chosen it
	    must also be supported by the client and probably the
	    only shared cipher suite. </p> <p> Captured TLS sessions
	    encrypted with ephemeral cipher suites (DHE or ECDHE) are
	    not at risk for subsequent decryption due to this
	    vulnerability. </p> <p> As a workaround if default cipher
	    suite configuration was used you can configure the server
	    to not use vulnerable suites with the ciphers option like
	    this: </p> <c> {ciphers, [Suite || Suite &lt;-
	    ssl:cipher_suites(), element(1,Suite) =/= rsa]} </c> <p>
	    that is your code will look somethingh like this: </p>
	    <c> ssl:listen(Port, [{ciphers, [Suite || Suite &lt;-
	    ssl:cipher_suites(), element(1,S) =/= rsa]} | Options]).

	    Integrate elliptic curve contribution from Andreas
	    Schultz </p>
          <p>
	    In order to be able to support elliptic curve cipher
	    suites in SSL/TLS, additions to handle elliptic curve
	    infrastructure has been added to public_key and crypto.</p>
          <p>
	    This also has resulted in a rewrite of the crypto API to
	    gain consistency and remove unnecessary overhead. All OTP
	    applications using crypto has been updated to use the new
	    API.</p>
          <p>
	    Impact: Elliptic curve cryptography (ECC) offers
	    equivalent security with smaller key sizes than other
	    public key algorithms. Smaller key sizes result in
	    savings for power, memory, bandwidth, and computational
	    cost that make ECC especially attractive for constrained
	    environments.</p>
