From the changelog of not yet released versions of MySQL: Important Change: Partitioning: Security Fix: It was possible, by creating a partitioned table using the DATA DIRECTORY and INDEX DIRECTORY options to gain privileges on other tables having the same name as the partitioned table. As a result of this fix, any table-level DATA DIRECTORY or INDEX DIRECTORY options are now ignored for partitioned tables. (Bug#32091, CVE-2007-5970) Mentioned in: MySQL 5.1.23 http://dev.mysql.com/doc/refman/5.1/en/news-5-1-23.html MySQL 6.0.4 http://dev.mysql.com/doc/refman/6.0/en/news-6-0-4.html Referenced MySQL bug report is not public at the moment: http://bugs.mysql.com/bug.php?id=32091
CVE description: CVE-2007-5970 MySQL 5.1.x before 5.1.23 and 6.0.x before 6.0.4 allows remote authenticated users to gain privileges on arbitrary tables via unspecified vectors involving use of table-level DATA DIRECTORY and INDEX DIRECTORY options when creating a partitioned table with the same name as a table on which the user lacks privileges.

This issue did not affect mysql packages as shipped in Red Hat Enterprise Linux 2.1, 3, 4, and 5, Red Hat Application Stack v1 and v2 and Fedora, as versions shipped do not support table partitioning. Partitioning feature was introduced in development MySQL version 5.1.
