MySQL 5.1 before 5.1.51 and 5.5 before 5.5.6 allows remote authenticated users to cause a denial of service (infinite loop) via multiple invocations of a (1) prepared statement or (2) stored procedure that creates a query with nested JOIN statements.

MySQL 5.0 before 5.0.92, 5.1 before 5.1.51, and 5.5 before 5.5.6 allows remote authenticated users to cause a denial of service (server crash) via a query that uses the (1) GREATEST or (2) LEAST function with a mixed list of numeric and LONGBLOB arguments, which is not properly handled when the function's result is "processed using an intermediate temporary table."

MySQL 5.0 before 5.0.92, 5.1 before 5.1.51, and 5.5 before 5.5.6 allows remote authenticated users to cause a denial of service (server crash) via a prepared statement that uses GROUP_CONCAT with the WITH ROLLUP modifier, probably triggering a use-after-free error when a copied object is modified in a way that also affects the original object.

MySQL 5.0 before 5.0.92, 5.1 before 5.1.51, and 5.5 before 5.5.6 allows remote authenticated users to cause a denial of service (assertion failure and server crash) via vectors related to view preparation, pre-evaluation of LIKE predicates, and IN Optimizers.

MySQL 5.1 before 5.1.51 and 5.5 before 5.5.6 allows remote authenticated users to cause a denial of service (mysqld server crash) by performing a user-variable assignment in a logical expression that is calculated and stored in a temporary table for GROUP BY, then causing the expression value to be used after the table is created, which causes the expression to be re-evaluated instead of accessing its value from the table.

Unspecified vulnerability in MySQL 5.0 before 5.0.92, 5.1 before 5.1.51, and 5.5 before 5.5.6 allows remote authenticated users to cause a denial of service (server crash) via vectors related to "materializing a derived table that required a temporary table for grouping" and "user variable assignments."

MySQL 5.0 before 5.0.92, 5.1 before 5.1.51, and 5.5 before 5.5.6 does not properly propagate type errors, which allows remote attackers to cause a denial of service (server crash) via crafted arguments to extreme-value functions such as (1) LEAST and (2) GREATEST, related to KILL_BAD_DATA and a "CREATE TABLE ... SELECT."

Oracle MySQL 5.1 before 5.1.49 and 5.5 before 5.5.5 sends an OK packet when a LOAD DATA INFILE request generates SQL errors, which allows remote authenticated users to cause a denial of service (mysqld daemon crash) via a crafted request.

Oracle MySQL 5.1 before 5.1.49 and 5.5 before 5.5.5 allows remote authenticated users to cause a denial of service (mysqld daemon crash) by using the HANDLER interface and performing "alternate reads from two indexes on a table," which triggers an assertion failure.

Oracle MySQL 5.1 before 5.1.49 allows remote authenticated users to cause a denial of service (mysqld daemon crash) by creating temporary tables with nullable columns while using InnoDB, which triggers an assertion failure.

Oracle MySQL 5.1 before 5.1.49 allows remote authenticated users to cause a denial of service (mysqld daemon crash) via certain arguments to the BINLOG command, which triggers an access of uninitialized memory, as demonstrated by valgrind.

Oracle MySQL 5.1 before 5.1.49 allows remote authenticated users to cause a denial of service (crash) via (1) IN or (2) CASE operations with NULL arguments that are explicitly specified or indirectly provided by the WITH ROLLUP modifier.

storage/innobase/dict/dict0crea.c in mysqld in Oracle MySQL 5.1 before 5.1.49 allows remote authenticated users to cause a denial of service (assertion failure) by modifying the (1) innodb_file_format or (2) innodb_file_per_table configuration parameters for the InnoDB storage engine, then executing a DDL statement.

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.

Buffer overflow in MySQL 5.0 through 5.0.91 and 5.1 before 5.1.47 allows remote authenticated users to execute arbitrary code via a COM_FIELD_LIST command with a long table name.

The my_net_skip_rest function in sql/net_serv.cc in MySQL 5.0 through 5.0.91 and 5.1 before 5.1.47 allows remote attackers to cause a denial of service (CPU and bandwidth consumption) by sending a large number of packets that exceed the maximum length.

Directory traversal vulnerability in MySQL 5.0 through 5.0.91 and 5.1 before 5.1.47 allows remote authenticated users to bypass intended table grants to read field definitions of arbitrary tables, and on 5.1 to read or delete content of arbitrary tables, via a .. (dot dot) in a table name.

MySQL 5.1.x before 5.1.41 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 originally associated with pathnames without symlinks, and that can point to tables created at a future time at which a pathname is modified to contain a symlink to a subdirectory of the MySQL data home directory, related to incorrect calculation of the mysql_unpacked_real_data_home value. NOTE: this vulnerability exists because of an incomplete fix for CVE-2008-4098 and CVE-2008-2079.

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.

mysqld in MySQL 5.0.x before 5.0.88 and 5.1.x before 5.1.41 does not (1) properly handle errors during execution of certain SELECT statements with subqueries, and does not (2) preserve certain null_value flags during execution of statements that use the GeomFromWKB function, which allows remote authenticated users to cause a denial of service (daemon crash) via a crafted statement.
