What is CVE-2015-3152?

A vulnerability exists in Oracle MySQL and MariaDB that arises from an inadequate implementation of SSL options. Specifically, the SSL configuration allows attackers to downgrade secure connections to an insecure state, facilitating man-in-the-middle attacks. This flaw, often referred to in security communities as a 'BACKRONYM' attack, enables malicious entities to spoof servers and potentially intercept sensitive communications. Users of affected MySQL and MariaDB versions should promptly review their SSL settings and apply the necessary updates to secure their environments.
