The installation scripts in the Gentoo dev-db/mysql, dev-db/mariadb, dev-db/percona-server, dev-db/mysql-cluster, and dev-db/mariadb-galera packages before 2017-09-29 have chown calls for user-writable directory trees, which allows local users to gain privileges by leveraging access to the mysql account for creation of a link.

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.

Unspecified vulnerability in the MySQL Connectors component in Oracle MySQL 5.1.34 and earlier allows remote authenticated users to affect confidentiality and integrity via unknown vectors related to Connector/J.

Oracle MySQL and MariaDB 5.5.x before 5.5.29, 5.3.x before 5.3.12, and 5.2.x before 5.2.14 does not modify the salt during multiple executions of the change_user command within the same connection which makes it easier for remote authenticated users to conduct brute force password guessing attacks.

Oracle MySQL 5.1 before 5.1.49 and 5.0 before 5.0.92 allows remote authenticated users to cause a denial of service (mysqld daemon crash) by using EXPLAIN with crafted "SELECT ... UNION ... ORDER BY (SELECT ... WHERE ...)" statements, which triggers a NULL pointer dereference in the Item_singlerow_subselect::store function.

Oracle MySQL 5.1 before 5.1.49 and 5.0 before 5.0.92 allows remote authenticated users to cause a denial of service (mysqld daemon crash) via a join query that uses a table with a unique SET column.

MySQL before 5.1.48 allows remote authenticated users with alter database privileges to cause a denial of service (server crash and database loss) via an ALTER DATABASE command with a #mysql50# string followed by a . (dot), .. (dot dot), ../ (dot dot slash) or similar sequence, and an UPGRADE DATA DIRECTORY NAME command, which causes MySQL to move certain directories to the server data directory.

MySQL before 5.1.46 allows local users to delete the data and index files of another user's MyISAM table via a symlink attack in conjunction with the DROP TABLE command, a different vulnerability than CVE-2008-4098 and CVE-2008-7247.

The mysql_uninstall_plugin function in sql/sql_plugin.cc in MySQL 5.1 before 5.1.46 does not check privileges before uninstalling a plugin, which allows remote attackers to uninstall arbitrary plugins via the UNINSTALL PLUGIN command.

The vio_verify_callback function in viosslfactories.c in MySQL 5.0.x before 5.0.88 and 5.1.x before 5.1.41, when OpenSSL is used, accepts a value of zero for the depth of X.509 certificates, which allows man-in-the-middle attackers to spoof arbitrary SSL-based MySQL servers via a crafted certificate, as demonstrated by a certificate presented by a server linked against the yaSSL library.

The mysql-ocaml bindings 1.0.4 for MySQL do not properly support the mysql_real_escape_string function, which might allow remote attackers to leverage escaping issues involving multibyte character encodings.

sql/item_xmlfunc.cc in MySQL 5.1 before 5.1.32 and 6.0 before 6.0.10 allows remote authenticated users to cause a denial of service (crash) via "an XPath expression employing a scalar expression as a FilterExpr with ExtractValue() or UpdateXML()," which triggers an assertion failure.

MySQL 4.1.x before 4.1.24, 5.0.x before 5.0.60, 5.1.x before 5.1.24, and 6.0.x before 6.0.5 allows local users to bypass certain privilege checks by calling CREATE TABLE on a MyISAM table with modified (1) DATA DIRECTORY or (2) INDEX DIRECTORY arguments that are within the MySQL home data directory, which can point to tables that are created in the future.

The convert_search_mode_to_innobase function in ha_innodb.cc in the InnoDB engine in MySQL 5.1.23-BK and earlier allows remote authenticated users to cause a denial of service (database crash) via a certain CONTAINS operation on an indexed column, which triggers an assertion error.

MySQL before 4.1.23, 5.0.x before 5.0.42, and 5.1.x before 5.1.18 does not require the DROP privilege for RENAME TABLE statements, which allows remote authenticated users to rename arbitrary tables.

The in_decimal::set function in item_cmpfunc.cc in MySQL before 5.0.40, and 5.1 before 5.1.18-beta, allows context-dependent attackers to cause a denial of service (crash) via a crafted IF clause that results in a divide-by-zero error and a NULL pointer dereference.

MySQL 5.x before 5.0.36 allows local users to cause a denial of service (database crash) by performing information_schema table subselects and using ORDER BY to sort a single-row result, which prevents certain structure elements from being initialized and triggers a NULL dereference in the filesort function.
