MariaDB Server 10.1.x < 10.1.19 Multiple DoS

Medium

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 10.1.x earlier than 10.1.19, and is therefore affected by multiple vulnerabilities :

- A flaw exists in the 'buf_page_is_checksum_valid*' function in 'buf0buf.cc' that is triggered during the handling of encrypted information. This may allow an authenticated attacker to cause a denial of service. (OSVDB 147133) - A flaw exists in the 'wsrep_replicate_myisam' functionality that is triggered when dropping 'myisam' tables. This may allow an authenticated attacker to crash the database. (OSVDB 147136)

Depending on the database's implementation, it varies if these vulnerabilitues require authenticated access (e.g. daily DBA duties) or may be exploited by a remote attacker (e.g. interfaced via a web application).

Solution

Upgrade to version 10.1.19 or later.
