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.
