MariaDB Server 5.5.x < 5.5.47 / 10.0.x < 10.0.22 / 10.1.x < 10.1.9 Multiple DoS

Medium Nessus Network Monitor Plugin ID 9295

Synopsis

The remote database server is affected by multiple Denial of Service (DoS) attack vectors.

Description

MariaDB is a community-developed fork of the MySQL relational database. The version of MariaDB installed on the remote host is 5.5.x earlier than 5.5.47, or 10.0.x earlier than 10.0.22, or 10.1.x earlier than 10.1.9, and is therefore affected by a flaw in the 'Item_field::fix_outer_field()' function in 'sql/item.cc' that is triggered when handling PREPARE statements. With a specially crafted query, an authenticated user can cause the database to crash and become unavailable.

Solution

Upgrade to version 10.1.9 or later. If version 10.1.x cannot be obtained, versions 10.0.22 and 5.5.47 have also been patched for these issues.
