NVD Description
Note: Versions mentioned in the description apply only to the upstream percona-xtradb-cluster-5.5 package and not the percona-xtradb-cluster-5.5 package as distributed by Ubuntu.
Oracle MySQL before 5.7.3, Oracle MySQL Connector/C (aka libmysqlclient) before 6.1.3, and MariaDB before 5.5.44 use the --ssl option to mean that SSL is optional, which allows man-in-the-middle attackers to spoof servers via a cleartext-downgrade attack, aka a "BACKRONYM" attack.
