[RHSA-2016:2595] mariadb security and bug fix update

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 (5.5.52). (BZ#1304516, BZ#1377974)

Security Fix(es):

• It was discovered that the MariaDB logging functionality allowed writing to MariaDB configuration files. An administrative database user, or a database user with FILE privileges, could possibly use this flaw to run arbitrary commands with root privileges on the system running the database server. (CVE-2016-6662)

• A race condition was found in the way MariaDB performed MyISAM engine table repair. A database user with shell access to the server running mysqld could use this flaw to change permissions of arbitrary files writable by the mysql system user. (CVE-2016-6663)

• 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-2016-3492, CVE-2016-5612, CVE-2016-5616, CVE-2016-5624, CVE-2016-5626, CVE-2016-5629, CVE-2016-8283)
