OpenSSL Cryptographic Issues Vulnerability - CVE-2016-0800
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 quotDROWNquot attack.
