sql/sql_table.cc in MySQL 5.0.x through 5.0.88, 5.1.x through 5.1.41, and 6.0 before 6.0.9-alpha, when the data home directory contains a symlink to a different filesystem, allows remote authenticated users to bypass intended access restrictions by calling CREATE TABLE with a (1) DATA DIRECTORY or (2) INDEX DIRECTORY argument referring to a subdirectory that requires following this symlink.

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 5.0 before 5.0.66, 5.1 before 5.1.26, and 6.0 before 6.0.6 does not properly handle a b'' (b single-quote single-quote) token, aka an empty bit-string literal, which allows remote attackers to cause a denial of service (daemon crash) by using this token in a SQL statement.

MySQL Server 5.1.x before 5.1.23 and 6.0.x before 6.0.4 does not check the rights of the entity executing BINLOG, which allows remote authorized users to execute arbitrary BINLOG statements.

MySQL 5.0.x before 5.0.51a, 5.1.x before 5.1.23, and 6.0.x before 6.0.4 does not update the DEFINER value of a view when the view is altered, which allows remote authenticated users to gain privileges via a sequence of statements including a CREATE SQL SECURITY DEFINER VIEW statement and an ALTER VIEW statement.

The federated engine in MySQL 5.0.x before 5.0.51a, 5.1.x before 5.1.23, and 6.0.x before 6.0.4, when performing a certain SHOW TABLE STATUS query, allows remote MySQL servers to cause a denial of service (federated handler crash and daemon crash) via a response that lacks the minimum required number of columns.

MySQL 5.1.x before 5.1.23 and 6.0.x before 6.0.4 allows remote authenticated users to gain privileges on arbitrary tables via unspecified vectors involving use of table-level DATA DIRECTORY and INDEX DIRECTORY options when creating a partitioned table with the same name as a table on which the user lacks privileges.

MySQL Community Server 5.0.x before 5.0.51, Enterprise Server 5.0.x before 5.0.52, Server 5.1.x before 5.1.23, and Server 6.0.x before 6.0.4, when a table relies on symlinks created through explicit DATA DIRECTORY and INDEX DIRECTORY options, allows remote authenticated users to overwrite system table information and gain privileges via a RENAME TABLE statement that changes the symlink to point to an existing file.
