Synopsis

Moderate: mariadb security and bug fix update

Type/Severity

Security Advisory: Moderate

Topic

An update for mariadb is now available for Red Hat Enterprise Linux 7.

Red Hat Product Security has rated this update as having a security impact of Moderate. 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.

Description

MariaDB is a multi-user, multi-threaded SQL database server that is binary compatible with MySQL.

The following packages have been upgraded to a later upstream version: mariadb (5.5.56). (BZ#1458933)

Security Fix(es):

• It was discovered that the mysql and mysqldump tools did not correctly handle database and table names containing newline characters. A database user with privileges to create databases or tables could cause the mysql command to execute arbitrary shell or SQL commands while restoring database backup created using the mysqldump tool. (CVE-2016-5483, CVE-2017-3600)
• 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-2016-5617, CVE-2016-6664)
• Multiple flaws were found in the way the MySQL init script handled initialization of the database data directory and permission setting on the error log file. The mysql operating system user could use these flaws to escalate their privileges to root. (CVE-2017-3265)
• It was discovered that the mysqld_safe script honored the ledir option value set in a MySQL configuration file. A user able to modify one of the MySQL configuration files could use this flaw to escalate their privileges to root. (CVE-2017-3291)
• Multiple flaws were found in the way the mysqld_safe script handled creation of error log file. The mysql operating system user could use these flaws to escalate their privileges to root. (CVE-2017-3312)
• A flaw was found in the way MySQL client library (libmysqlclient) handled prepared statements when server connection was lost. A malicious server or a man-in-the-middle attacker could possibly use this flaw to crash an application using libmysqlclient. (CVE-2017-3302)
• This update fixes several vulnerabilities in the MariaDB database server. Information about these flaws can be found on the Oracle Critical Patch Update Advisory page, listed in the References section. (CVE-2017-3238, CVE-2017-3243, CVE-2017-3244, CVE-2017-3258, CVE-2017-3308, CVE-2017-3309, CVE-2017-3313, CVE-2017-3317, CVE-2017-3318, CVE-2017-3453, CVE-2017-3456, CVE-2017-3464)
