5.1.22. Changes in MySQL 5.0.50sp1 [QSP] (12 December 2007)

This is a Service Pack release of the MySQL Enterprise Server 5.0.

Bugs fixed:

  • Security Fix: Using RENAME TABLE against a table with explicit DATA DIRECTORY and INDEX DIRECTORY options can be used to overwrite system table information by replacing the symbolic link points. the file to which the symlink points.

    MySQL will now return an error when the file to which the symlink points already exists. (Bug#32111, CVE-2007-5969)

  • Security Fix: ALTER VIEW retained the original DEFINER value, even when altered by another user, which could allow that user to gain the access rights of the view. Now ALTER VIEW is allowed only to the original definer or users with the SUPER privilege. (Bug#29908)

  • Security Fix: When using a FEDERATED table, the local server could be forced to crash if the remote server returned a result with fewer columns than expected. (Bug#29801)
