A vulnerability was found in MariaDB. An OpenVAS port scan on ports 3306 and 4567 allows a malicious remote client to cause a denial of service.

MariaDB Server before 10.7 is vulnerable to Denial of Service. While executing the plugin/server_audit/server_audit.c method log_statement_ex, the held lock lock_bigbuffer is not released correctly, which allows local users to trigger a denial of service due to the deadlock.

MariaDB Server before 10.7 is vulnerable to Denial of Service. In extra/mariabackup/ds_compress.cc, when an error occurs (i.e., going to the err label) while executing the method create_worker_threads, the held lock thd->ctrl_mutex is not released correctly, which allows local users to trigger a denial of service due to the deadlock.

MariaDB Server before 10.7 is vulnerable to Denial of Service. In extra/mariabackup/ds_compress.cc, when an error occurs (pthread_create returns a nonzero value) while executing the method create_worker_threads, the held lock is not released correctly, which allows local users to trigger a denial of service due to the deadlock.

MariaDB Server before 10.7 is vulnerable to Denial of Service. In extra/mariabackup/ds_xbstream.cc, when an error occurs (stream_ctxt->dest_file == NULL) while executing the method xbstream_open, the held lock is not released correctly, which allows local users to trigger a denial of service due to the deadlock.

MariaDB Server v10.9 and below was discovered to contain a segmentation fault via the component sql/item_func.cc:148.

An issue in the component Used_tables_and_const_cache::used_tables_and_const_cache_join of MariaDB Server v10.7 and below was discovered to allow attackers to cause a Denial of Service (DoS) via specially crafted SQL statements.

MariaDB through 10.5.9 allows attackers to trigger a convert_const_to_int use-after-free when the BIGINT data type is used.

MariaDB before 10.6.5 has a sql_lex.cc integer overflow, leading to an application crash.

MariaDB before 10.6.2 allows an application crash because of mishandling of a pushdown from a HAVING clause to a WHERE clause.

MariaDB before 10.7.2 allows an application crash because it does not recognize that SELECT_LEX::nest_level is local to each VIEW.

get_sort_by_table in MariaDB before 10.6.2 allows an application crash via certain subquery uses of ORDER BY.

If, after successful installation of MantisBT through 2.5.2 on MySQL/MariaDB, the administrator does not remove the 'admin' directory (as recommended in the "Post-installation and upgrade tasks" section of the MantisBT Admin Guide), and the MySQL client has a local_infile setting enabled (in php.ini mysqli.allow_local_infile, or the MySQL client config file, depending on the PHP setup), an attacker may take advantage of MySQL's "connect file read" feature to remotely access files on the MantisBT server.
