Scientific Linux Security Update : mariadb on SL7.x x86_64

This script is Copyright (C) 2017 Tenable Network Security, Inc.


Synopsis :

The remote Scientific Linux host is missing one or more security
updates.

Description :

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

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)

(CVE-2017-3238, CVE-2017-3243, CVE-2017-3244, CVE-2017-3258,
