MariaDB Server 10.1.x < 10.1.22 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 10.1.22, and is therefore affected by multiple vulnerabilities :

- A flaw exists in the 'JOIN_CACHE::create_remaining_fields()' function in 'sql_join_cache.cc' that is triggered when handling data caching.This may allow an authenticated attacker to crash the database.(OSVDB 153428) - A flaw exists in the 'find_field_in_tables()' function in 'sql_base.cc' that is triggered during the handling of stored procedures in 'EXISTS' queries.This may allow an authenticated attacker to crash the database.(OSVDB 153981) - A flaw exists in the 'JOIN::drop_unused_derived_keys()' function in 'sql_select.cc' that is triggered during the handling of a specially crafted 'SELECT' statement.This may allow an authenticated attacker to crash the database.(OSVDB 153992)

解決方案

Upgrade to version 10.1.22 or later.
