"An update for mysql is now available for Red Hat Enterprise Linux 6.

Red Hat Product Security has rated this update as having a security
impact of Important. A Common Vulnerability Scoring System (CVSS) base
score, which gives a detailed severity rating, is available for each
vulnerability from the CVE link(s) in the References section.

MySQL is a multi-user, multi-threaded SQL database server. It consists
of the MySQL server daemon (mysqld) and many client programs and
libraries.

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)

* A race condition was found in the way MySQL 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, CVE-2016-5616)

Note that Tenable Network Security has attempted to extract the
preceding description block directly from the corresponding Red Hat
security advisory. Virtuozzo provides no description for VZLSA
advisories. Tenable has attempted to automatically clean and format
it as much as possible without introducing additional issues.");
