MariaDB 10.1.x < 10.1.5 wait_for_workers_idle() Function Worker Thread Handling DoS

medium Nessus Plugin ID 84797

Synopsis

The remote database server is affected by a denial of service vulnerability.

Description

The version of MariaDB running on the remote host is 10.1.x prior to 10.1.5. It is, therefore, affected by a denial of service vulnerability due to a flaw in the wait_for_workers_idle() function that occurs when handling worker threads. An authenticated, remote attacker can exploit this to crash the database.

Solution

Upgrade to MariaDB version 10.1.5 or later.
