Mariadb : Security Vulnerabilities, CVEs, Published In 2012

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.

Heap-based buffer overflow in Oracle MySQL 5.5.19 and other versions through 5.5.28, and MariaDB 5.5.28a and possibly other versions, allows remote authenticated users to cause a denial of service (memory corruption and crash) and possibly execute arbitrary code, as demonstrated using certain variations of the (1) USE, (2) SHOW TABLES, (3) DESCRIBE, (4) SHOW FIELDS FROM, (5) SHOW COLUMNS FROM, (6) SHOW INDEX FROM, (7) CREATE TABLE, (8) DROP TABLE, (9) ALTER TABLE, (10) DELETE FROM, (11) UPDATE, and (12) SET PASSWORD commands.

Stack-based buffer overflow in the acl_get function in Oracle MySQL 5.5.19 and other versions through 5.5.28, and 5.1.53 and other versions through 5.1.66, and MariaDB 5.5.2.x before 5.5.28a, 5.3.x before 5.3.11, 5.2.x before 5.2.13 and 5.1.x before 5.1.66, allows remote authenticated users to execute arbitrary code via a long argument to the GRANT FILE command.

Unspecified vulnerability in the MySQL Server component in Oracle MySQL 5.1.64 and earlier, and 5.5.26 and earlier, allows remote authenticated users to affect availability via unknown vectors related to Server Replication.

Unspecified vulnerability in the MySQL Server component in Oracle MySQL 5.1.65 and earlier, and 5.5.27 and earlier, allows remote authenticated users to affect availability via unknown vectors related to Server Optimizer.

Unspecified vulnerability in the MySQL Server component in Oracle MySQL 5.1.65 and earlier, and 5.5.27 and earlier, allows remote authenticated users to affect availability via unknown vectors related to Server.

Unspecified vulnerability in the MySQL Server component in Oracle MySQL 5.1.63 and earlier, and 5.5.25 and earlier, allows remote authenticated users to affect availability via unknown vectors related to InnoDB Plugin.

Unspecified vulnerability in the MySQL Server component in Oracle MySQL 5.1.63 and earlier, and 5.5.25 and earlier, allows remote authenticated users to affect availability via unknown vectors related to Server Full Text Search.

Unspecified vulnerability in the MySQL Server component in Oracle MySQL 5.1.63 and earlier, and 5.5.25 and earlier, allows remote authenticated users to affect availability via unknown vectors related to InnoDB.

Unspecified vulnerability in the MySQL Server component in Oracle MySQL 5.1.64 and earlier, and 5.5.26 and earlier, allows remote authenticated users to affect confidentiality, integrity, and availability via unknown vectors related to Information Schema.

Unspecified vulnerability in the MySQL Server component in Oracle MySQL 5.1.65 and earlier, and 5.5.27 and earlier, allows local users to affect confidentiality via unknown vectors related to Server Installation.

Unspecified vulnerability in the MySQL Server component in Oracle MySQL 5.1.64 and earlier, and 5.5.26 and earlier, allows remote attackers to affect confidentiality, integrity, and availability via unknown vectors related to Protocol.

Unspecified vulnerability in the MySQL Server component in Oracle MySQL 5.1.64 and earlier, and 5.5.26 and earlier, allows remote authenticated users to affect availability via unknown vectors related to Server Optimizer.

Unspecified vulnerability in MySQL 5.5.x before 5.5.23 has unknown impact and attack vectors related to a "Security Fix", aka Bug #59533. NOTE: this might be a duplicate of CVE-2012-1689, but as of 20120816, Oracle has not commented on this possibility.

sql/password.c in Oracle MySQL 5.1.x before 5.1.63, 5.5.x before 5.5.24, and 5.6.x before 5.6.6, and MariaDB 5.1.x before 5.1.62, 5.2.x before 5.2.12, 5.3.x before 5.3.6, and 5.5.x before 5.5.23, when running in certain environments with certain implementations of the memcmp function, allows remote attackers to bypass authentication by repeatedly authenticating with the same incorrect password, which eventually causes a token comparison to succeed due to an improperly-checked return value.

Unspecified vulnerability in Oracle MySQL Server 5.5.23 and earlier allows remote authenticated users to affect availability via unknown vectors related to InnoDB.

Unspecified vulnerability in Oracle MySQL Server 5.5.23 and earlier allows remote authenticated users to affect availability via unknown vectors.

Unspecified vulnerability in Oracle MySQL Server 5.1.62 and earlier, and 5.5.23 and earlier, allows remote authenticated users to affect availability via unknown vectors related to Server Optimizer.

Unspecified vulnerability in the MySQL Server component in Oracle MySQL 5.1.61 and earlier, and 5.5.21 and earlier, allows remote authenticated users to affect availability via unknown vectors related to Server Optimizer, a different vulnerability than CVE-2012-1690.

Unspecified vulnerability in the MySQL Server component in Oracle MySQL 5.5.21 and earlier allows remote authenticated users to affect availability via unknown vectors related to Partition.

Unspecified vulnerability in the MySQL Server component in Oracle MySQL 5.1.61 and earlier, and 5.5.21 and earlier, allows remote authenticated users to affect availability via unknown vectors related to Server Optimizer, a different vulnerability than CVE-2012-1703.

Unspecified vulnerability in Oracle MySQL Server 5.1.62 and earlier, and 5.5.22 and earlier, allows remote authenticated users to affect availability via unknown vectors related to Server Optimizer.
