3. Description:

MariaDB is a multi-user, multi-threaded SQL database server that is binary compatible with MySQL.

The following packages have been upgraded to a newer upstream version: MariaDB (5.5.47). Refer to the MariaDB Release Notes listed in the References section for a complete list of changes.

Security Fix(es):

* 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. (CVE-2016-2047)

* This update fixes several vulnerabilities in the MariaDB database server. Information about these flaws can be found on the Oracle Critical Patch Update Advisory page, listed in the References section. (CVE-2015-4792, CVE-2015-4802, CVE-2015-4815, CVE-2015-4816, CVE-2015-4819, CVE-2015-4826, CVE-2015-4830, CVE-2015-4836, CVE-2015-4858, CVE-2015-4861, CVE-2015-4870, CVE-2015-4879, CVE-2015-4913, CVE-2016-0505, CVE-2016-0546, CVE-2016-0596, CVE-2016-0597, CVE-2016-0598, CVE-2016-0600, CVE-2016-0606, CVE-2016-0608, CVE-2016-0609, CVE-2016-0616)

Bug Fix(es):

* When more than one INSERT operation was executed concurrently on a non-empty InnoDB table with an AUTO_INCREMENT column defined as a primary key immediately after starting MariaDB, a race condition could occur. As a consequence, one of the concurrent INSERT operations failed with a "Duplicate key" error message. A patch has been applied to prevent the race condition. Now, each row inserted as a result of the concurrent INSERT operations receives a unique primary key, and the operations no longer fail in this scenario. (BZ#1303946)

4. Solution:

For details on how to apply this update, which includes the changes described in this advisory, refer to:

After installing this update, the MariaDB server daemon (mysqld) will be restarted automatically.
