Oracle Plan Bug Fixes for MySQL

Oracle have revealed that the upcoming MySQL 5.1.47 release will fix several security holes.

Bugs fixed, include the failure of a REVOKE statement being logged as the wrong error code, and InnoD’s tendency to choose off-page storage without first checking for an “off-page storage” flag in the record header. It also fixes a memory leak that occurred due to missing deallocation of the comparators array.

In this version, the InnoDB plugin will store redo log records in a hash table during recovery. More information is available at the Changes log.
