Red Hat Security Advisory 2016-1481-01 – MariaDB is a multi-user, multi-threaded SQL database server. For all practical purposes, MariaDB is binary-compatible with MySQL. The following packages have been upgraded to a newer upstream version: mariadb55-mariadb. Security Fix: It was found that the MariaDB client library did not properly check host names against server identities noted in the X.509 certificates when establishing secure connections using TLS/SSL. A man-in-the-middle attacker could possibly use this flaw to impersonate a server to a client.
