Hello,
Why MySQL 5.0.23 while it has serious bug?
I thought you guys will release 5.0.24 instead.
Security fix: If a user has access to MyISAM table t, that user can create a
MERGE table m that accesses t. However, if the user's privileges on t are
subsequently revoked, the user can continue to access t by doing so through m.
If this behavior is undesirable, you can start the server with the new
--skip-merge option to disable the MERGE storage engine. (Bug#15195)
MySQL 5.0.23 contained a fix for Bug#10952 that has been reverted in 5.0.24
because it introduced the risk of unintended data loss.
Thank you,
