|The SSLv2 protocol, as used in OpenSSL before 1.0.1s and 1.0.2 before
1.0.2g and other products, requires a server to send a ServerVerify
message before establishing that a client possesses certain plaintext
RSA data, which makes it easier for remote attackers to decrypt TLS
ciphertext data by leveraging a Bleichenbacher RSA padding oracle, aka
a "DROWN" attack.
