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.
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.
The mysqlchangedb function in MySQL 5.0.x before 5.0.40 and 5.1.x before 5.1.18 does not restore THD::dbaccess privileges when returning from SQL SECURITY INVOKER stored routines, which allows remote authenticated users to gain privileges.
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 COMFIELDLIST command with a long table name.
The mynetskiprest function in sql/netserv.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.
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.
Unspecified vulnerability in the MySQL Server component in Oracle MySQL 5.5.19 and earlier allows remote authenticated users to affect availability via unknown vectors related to Server Optimizer.
A denial of service flaw was found in the way MySQL processed EXPLAIN statements for SQL queries of the form:
SELECT ... UNION ... ORDER BY (SELECT ... WHERE ...)
A remote authenticated MySQL user could use this flaw to cause mysqld deamon crash (dereference NULL pointer).

Note: This issue only causes a temporary denial of service, as the mysql daemon shipped with Red Hat Enterprise Linux 5 will be automatically restarted after the crash.
A denial of service flaw was found in the way MySQL processed joins queries, which involved a table with unique SET column. A remote MySQL user could use this flaw to cause mysqld daemon crash.

MySQL before 5.1.46 allows local users to delete the data and index files of another user's MyISAM table via a symlink attack in conjunction with the DROP TABLE command, a different vulnerability than CVE-2008-4098 and CVE-2008-7247.
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.
MySQL 5.x before 5.0.36 allows local users to cause a denial of service (database crash) by performing informationschema 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.
