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. - 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. - 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.
