The mysql_change_db function in MySQL 5.0.x before 5.0.40 and 5.1.x before 5.1.18 does not restore THD::db_access privileges when returning from SQL SECURITY INVOKER stored routines, which allows remote authenticated users to gain privileges.
MySQL before 5.1.18 allows remote authenticated users without SELECT privileges to obtain sensitive information from partitioned tables via an ALTER TABLE statement.
MySQL 5.x before 5.0.36 allows local users to cause a denial of service (database crash) by performing information_schema table subselects and using ORDER BY to sort a single-row result, which prevents certain structure elements from being initialized and triggers a NULL dereference in the filesort function.
sql_select.cc in MySQL 5.0.x before 5.0.32 and 5.1.x before 5.1.14 allows remote authenticated users to cause a denial of service (crash) via an EXPLAIN SELECT FROM on the INFORMATION_SCHEMA table, as originally demonstrated using ORDER BY.
Buffer overflow in SAP DB and MaxDB before 7.6.00.30 allows remote attackers to execute arbitrary code via a long database name when connecting via a WebDBM client.
MySQL before 4.1.21, 5.0 before 5.0.25, and 5.1 before 5.1.12, when run on case-sensitive filesystems, allows remote authenticated users to create or access a database when the database name differs only in case from a database for which they have permissions.
MySQL before 5.0.25 and 5.1 before 5.1.12 evaluates arguments of suid routines in the security context of the routine's definer instead of the routine's caller, which allows remote authenticated users to gain privileges through a routine that has been made available using GRANT EXECUTE.
MySQL 4.1 before 4.1.21 and 5.0 before 5.0.24 allows a local user to access a table through a previously created MERGE table, even after the user's privileges are revoked for the original table, which might violate intended security policy.
Format string vulnerability in time.cc in MySQL Server 4.1 before 4.1.21 and 5.0 before 1 April 2006 allows remote authenticated users to cause a denial of service (crash) via a format string instead of a date as the first parameter to the date_format function, which is later used in a formatted print call to display the error message.
