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.

With MariaDB running on Windows, when local clients connect to the server over named pipes, it's possible for an unprivileged user with an ability to run code on the server machine to intercept the named pipe connection and act as a man-in-the-middle, gaining access to all the data passed between the client and the server, and getting the ability to run SQL commands on behalf of the connected user. This occurs because of an incorrect security descriptor. This affects MariaDB Server before 10.1.48, 10.2.x before 10.2.35, 10.3.x before 10.3.26, 10.4.x before 10.4.16, and 10.5.x before 10.5.7. NOTE: this issue exists because certain details of the MariaDB CVE-2019-2503 fix did not comprehensively address attack variants against MariaDB. This situation is specific to MariaDB, and thus CVE-2020-28912 does NOT apply to other vendors that were originally affected by CVE-2019-2503.

sql/event_data_objects.cc in MariaDB before 10.1.30 and 10.2.x before 10.2.10 and Percona XtraDB Cluster before 5.6.37-26.21-3 and 5.7.x before 5.7.19-29.22-3 allows remote authenticated users with SQL access to bypass intended access restrictions and replicate data definition language (DDL) statements to cluster nodes by leveraging incorrect ordering of DDL replication and ACL checking.

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.

Crash in libmysqlclient.so in Oracle MySQL before 5.6.21 and 5.7.x before 5.7.5 and MariaDB through 5.5.54, 10.0.x through 10.0.29, 10.1.x through 10.1.21, and 10.2.x through 10.2.3.

mysqld_safe in Oracle MySQL through 5.5.51, 5.6.x through 5.6.32, and 5.7.x through 5.7.14; MariaDB; Percona Server before 5.5.51-38.2, 5.6.x before 5.6.32-78-1, and 5.7.x before 5.7.14-8; and Percona XtraDB Cluster before 5.5.41-37.0, 5.6.x before 5.6.32-25.17, and 5.7.x before 5.7.14-26.17, when using file-based logging, allows local users with access to the mysql account to gain root privileges via a symlink attack on error logs and possibly other files.
