MariaDB Server 10.1.x < 10.1.17 Multiple DoS

High

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. (OSVDB 143528) - 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. (OSVDB 143529) - 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. (OSVDB 143530) - 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. (OSVDB 143531) - 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. (OSVDB 143736) - 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. (OSVDB 143755) - 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. (OSVDB 143756)

Solution

Upgrade to version 10.1.17 or later.
