CVE-2016-0704 is a medium-severity vulnerability affecting OpenSSL versions before 0.9.8zf, 1.0.0r, 1.0.1m, and 1.0.2a. It involves an oracle protection mechanism flaw in the SSLv2 implementation that, when using export cipher suites, overwrites incorrect MASTER-KEY bytes. This makes it easier for remote attackers to decrypt TLS ciphertext data by leveraging a Bleichenbacher RSA padding oracle attack. The attack has high complexity but can lead to high confidentiality impact, with no known active exploitation, publicly available exploit code, or significant community discussion.
