| Description: | Summary:
The remote host is missing an update for the 'mariadb'
package(s) announced via the referenced advisory.
Vulnerability Insight:
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,
