Synopsis :

The remote Red Hat host is missing one or more security updates.

Description :

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)
