MariaDB 是一个采用 Maria 存储引擎的 MySQL 分支版本，是由原来 MySQL 的作者 Michael Widenius 创办的公司所开发的免费开源的数据库服务器。
MariaDB 5.1.44b fixes a buffer overflow that might potentially allow an authenticated user to run arbitrary code inside the server. It also has a fix for MySQL Bug #53371: "Security hole with bypassing grants using special path in db/table names." In all other respects, it is the same as MariaDB 5.1.44.
