The version of MariaDB running on the remote host is 5.5.x prior to 5.5.51. It is, therefore, affected by multiple vulnerabilities:
A flaw exists in the check_log_path() function within file sql/sys_vars.cc due to inadequate restrictions on the ability to write to the my.cnf configuration file and allowing the loading of configuration files from path locations not used by current versions. An authenticated, remote attacker can exploit this issue by using specially crafted queries that utilize logging functionality to create new files or append custom content to existing files. This allows the attacker to gain root privileges by inserting a custom .cnf file with a ‘malloc_lib=’ directive pointing to specially crafted mysql_hookandroot_lib.so file and thereby cause MySQL to load a malicious library the next time it is started. (CVE-2016-6662)
A denial of service vulnerability exists in the emb_stmt_execute() function in file libmysqld/lib_sql.cc when handling queries. An authenticated, remote attacker can exploit this 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.
