MySQL is a multi-user, multi-threaded SQL database server. It consists of the MySQL server daemon, mysqld, and many client programs.
The following packages have been upgraded to a newer upstream version: mysql55-mysql (5.5.52).
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)
