Red Hat: RHSA-2016-2061-01 Critical: postgresql Vulnerability Exploit

A significant update addressing security vulnerabilities and bugs in mariadb-galera has been launched for Red Hat OpenStack Platform 6.0, with essential implications.
An update for mariadb-galera is now available for Red Hat Enterprise Linux OpenStack Platform 6.0 (Juno) for RHEL 7

Solution

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

https://access.redhat.com/articles/11258

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

Summary

MariaDB is a multi-user, multi-threaded SQL database server that is binary compatible with MySQL. Galera is a synchronous multi-master cluster for MariaDB.
Security Fix(es):
* It was discovered that the MySQL logging functionality allowed writing to MySQL 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)
Bug Fix(es):
* Because Red Hat Enterprise Linux 7.3 changed the return format of the "systemctl is-enabled" command as consumed by shell scripts, the mariadb-galera RPM package, upon installation, erroneously detected that the MariaDB service was enabled when it was not. As a result, the Red Hat OpenStack Platform installer, which then tried to run mariadb-galera using Pacemaker and not systemd, failed to start Galera. With this update, mariadb-galera's RPM installation scripts now use a different systemctl command, correctly detecting the default MariaDB as disabled, and the installer can succeed. (BZ#1376909)
* Previously, both the mariadb-server and mariadb-galera-server packages shipped the client-facing libraries, dialog.so and mysql_clear_password.so. As a result, the mariadb-galera-server package would fail to install because of package conflicts. With this update, these libraries have been moved from mariadb-galera-server to mariadb-libs, and the mariadb-galera-server package installs successfully. (BZ#1376903)
