Log Message:
Update mysql5-server pacakge to 5.0.67.

This is security fix.

For complete changes, please refer
http://dev.mysql.com/doc/refman/5.0/en/releasenotes-cs-5-0-67.html.
Here is a part of it.

Functionality added or changed:

Security Enhancement:

  To enable stricter control over the location from which user-defined
  functions can be loaded, the plugin_dir system variable has been
  backported from MySQL 5.1. If the value is non-empty, user-defined
  function object files can be loaded only from the directory named by this
  variable. If the value is empty, the behavior that is used before 5.0.67
  applies: The UDF object files must be located in a directory that is
  searched by your system's dynamic linker. (Bug#37428)

Important Change: Incompatible Change:

  The FEDERATED storage engine is now disabled by default in the .cnf files
  shipped with MySQL distributions (my-huge.cnf, my-medium.cnf, and so
  forth). This affects server behavior only if you install one of these
  files. (Bug#37069)

Cluster API: Important Change:

  Because NDB_LE_MemoryUsage.page_size_kb shows memory page sizes in bytes
  rather than kilobytes, it has been renamed to page_size_bytes. The name
  page_size_kb is now deprecated and thus subject to removal in a future
  release, although it currently remains supported for reasons of backward
  compatibility. See The Ndb_logevent_type Type, for more information about
  NDB_LE_MemoryUsage. (Bug#30271)

Important Change:

  Some changes were made to CHECK TABLE ... FOR UPGRADE and REPAIR TABLE
  with respect to detection and handling of tables with incompatible .frm
  files (files created with a different version of the MySQL server). These
  changes also affect mysqlcheck because that program uses CHECK TABLE and
  REPAIR table, and thus also mysql_upgrade because that program invokes
  mysqlcheck.
