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 10.0.x prior to 10.0.27, and is therefore affected by multiple DoS vulnerabilities :- A flaw exists in the 'emb_stmt_execute()' function in 'libmysqld/lib_sql.cc' that is triggered during the handling of queries. This may allow an authenticated attacker to crash the database.
- 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 the 'my_double_round()' function in 'sql/item_func.cc' that is triggered during the handling of specially crafted queries. This may allow an authenticated attacker to crash the database.
- A denial of service vulnerability exists in the 'st_select_lex_unit::cleanup()' function within file 'sql/sql_union.cc' when handling 'UNION' queries during 'JOIN' cleanup. An authenticated, remote attacker can exploit this to crash the database.
