## Overview

MariaDB server is a community developed fork of MySQL server. In versions 3.3.18 and 3.4.8, an application that was taking non-validated user input, escaping it with mysql_real_escape_string() and sending it to the database using text protocol and big5 character set was vulnerable to SQL injections, even though mysql_real_escape_string() was supposed to prevent them. This issue has been patched in versions 3.3.19 and 3.4.9.

## Affected

- `mariadb = 3.3.18`
- `mariadb = 3.4.8`
- `enterprise_linux = 10.0`
