A security issue has been reported in MySQL, which can be exploited by malicious, local users to bypass certain security restrictions.
The problem is that it is possible to bypass certain privilege checks by creating a MyISAM table with certain DATA DIRECTORY and INDEX DIRECTORY options to overwrite existing table files in the MySQL data directory.
The security issue is reported in versions prior to 4.1.24 and 5.0.60.
Solution: Update to version 5.1.41.
