MariaDB 5.1.44b Linux and Solaris binaries, Ubuntu/Debian/CentOS packages, and source are now available for download. This is a bugfix/security release of MariaDB 5.1.44. From the MariaDB 5.1.44b Release Notes:
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.
See the MariaDB 5.1.44 Release Notes for a summary of the differences between MariaDB 5.1.42 and MariaDB 5.1.44.
A Windows binary is coming soon.
