Oracle MySQL 5.5.38 and earlier, 5.6.19 and earlier, and MariaDB 5.5.28a, 5.3.11, 5.2.13, 5.1.66, and possibly other versions, generates different error messages with different time delays depending on whether a user name exists, which allows remote attackers to enumerate valid usernames.

Oracle MySQL 5.1.67 and earlier and 5.5.29 and earlier, and MariaDB 5.5.28a and possibly other versions, allows remote authenticated users to cause a denial of service (mysqld crash) via a SELECT command with an UpdateXML command containing XML with a large number of unique, nested elements.

MySQL 5.5.19 and possibly other versions, and MariaDB 5.5.28a and possibly other versions, when configured to assign the FILE privilege to users who should not have administrative privileges, allows remote authenticated users to gain privileges by leveraging the FILE privilege to create files as the MySQL administrator. NOTE: the vendor disputes this issue, stating that this is only a vulnerability when the administrator does not follow recommendations in the product's installation documentation. NOTE: it could be argued that this should not be included in CVE because it is a configuration issue.
