Red Hat: RHSA-2016:2749-01 Important: mysqld Security Threats

red hat
Calendar Grey November 15, 2016
Scroller Redhat
Important security patch for rh-postgresql12-postgres mitigates several vulnerabilities and strengthens overall defense.
An update for rh-mysql56-mysql is now available for Red Hat Software Collections

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 MySQL server daemon (mysqld) will be restarted automatically.

Summary

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: rh-mysql56-mysql (5.6.34).
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)
* A flaw was found in the way the mysqld_safe script handled creation of error log file. The mysql operating system user could use this flaw to escalate their privileges to root. (CVE-2016-6664, CVE-2016-5617)
* This update fixes several vulnerabilities in the MySQL database server. Information about these flaws can be found on the Oracle Critical Patch Update Advisory pages, listed in the References section. (CVE-2016-3492, CVE-2016-5507, CVE-2016-5626, CVE-2016-5629, CVE-2016-8283)
