MariaDB Server 10.0.x < 10.0.22 Multiple DoS Vulnerabilities

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 earlier than 10.0.22, and is therefore affected by the following denial of service vulnerabilities :

- Multiple denial ofservice vulnerabilities exist due to multiple unspecified flaws in the 'Server : Partition'subcomponent. An authenticated, remote attacker can exploit these flaws to affect availability. (CVE-2015-4792, CVE-2015-4802) - A denial of service vulnerability exists due to an unspecified flaw in the Query Cache subcomponent. An authenticated, remote attacker can exploit this to affect availability. (CVE-2015-4807) - A denial of service vulnerability exists due to an unspecified flaw in the DDL subcomponent. An authenticated, remote attacker can exploit this to affect availability. (CVE-2015-4815) - An information disclosure vulnerability exists due to an unspecified flaw in the Types subcomponent. An authenticated, remote attacker can exploit this to gain access to sensitive information. (CVE-2015-4826) - An unspecified vulnerability exists due to an unspecified flaw in the 'Security : Privileges' subcomponent. An authenticated, remote attacker can exploit this to affect integrity. (CVE-2015-4830) - A denial of service vulnerability exists due to an unspecified flaw in the SP subcomponent. An authenticated, remote attacker can exploit this to affect availability. (CVE-2015-4836) - Multiple denial of service vulnerabilities exist due to multiple unspecified flaws in the DML subcomponent. An authenticated, remote attacker can exploit these flaws to affect availability. (CVE-2015-4858, CVE-2015-4913) - A denial of service vulnerability exists due to an unspecified flaw in the InnoDB subcomponent. An authenticated, remote attacker can exploit this to affect availability. (CVE-2015-4861) - A denial of service vulnerability exists due to an unspecified flaw in the 'Server : Parser' subcomponent. An authenticated, remote attacker can exploit this to affect availability. (CVE-2015-4870) - A denial of service vulnerability exists due to a flaw in the 'convert_kill_to_deadlock_error()' function that is triggered when handling rollbacks. An authenticated, remote attacker can exploit this, via a specially crafted query, to cause the database to crash. (OSVDB 129717) - A denial of service vulnerability exists due to a flaw in the 'no_rows_in_result()' function that is triggered when handling logical conditions. An authenticated, remote attacker can exploit this, via a specially crafted query, to cause the database to crash. (OSVDB 129718)

Solution

Upgrade to version 10.0.22 or later.
