Vulnerability Details

CVEID: CVE-2016-0800 DESCRIPTION: OpenSSL could allow a remote attacker to bypass security restrictions. By using a server that supports SSLv2 and EXPORT cipher suites as a Bleichenbacher RSA padding oracle, an attacker could exploit this vulnerability to decrypt TLS sessions between clients and non-vulnerable servers. This vulnerability is also known as the DROWN attack.
