MariaDB Server 10.1.x < 10.1.17 Multiple DoS

high Nessus Network Monitor Plugin ID 9546

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 10.1.17, and is therefore affected by multiple vulnerabilities :

- A NULL pointer dereference flaw exists in the 'innobase_need_rebuild()' function that is triggered during the handling of renamed columns. This may allow an authenticated attacker to crash the database.
- A flaw exists in the 'ha_myisam::enable_indexes()' function in 'storage/myisam/ha_myisam.cc' that is triggered during the handling of ALTER TABLE statements. This may allow an authenticated attacker to crash the database.
- An unspecified flaw exists in the 'check_log_path()' function in 'sql/sys_vars.cc' that may allow an authenticated attacker to have an unspecified impact related to the 'general_log_file'. No further details have been provided.
- A flaw exists in the 'Item_sum_std::val_real()' function in 'sql/item_sum.cc' that is triggered during the handling of SUM statements. This may allow an authenticated attacker to crash the database.
- A flaw exists in 'sql/item_subselect.cc' that is triggered during the handling of specially crafted queries for non-existent functions. This may allow an authenticated attacker to crash the database.
- A flaw exists in the 'Item_subselect::is_expensive()' function in 'sql/item_subselect.cc' that is triggered during the handling of optimization procedures. This may allow an authenticated attacker to crash the database.
- A flaw exists in the 'st_select_lex_unit::cleanup()' function in 'sql/sql_union.cc' that is triggered during the handling of 'UNION' queries during 'JOIN' cleanup. This may allow an authenticated attacker to crash the database.

Solution

Upgrade to version 10.1.17 or later.
