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.
The product attempts to access a file based on the filename, but it does not properly prevent that filename from identifying a link or shortcut that resolves to an unintended resource.
