Dear MySQL users,

MySQL Community Server 5.0.51a, a new version of the popular Open Source
Database Management System, has been released. The release is now
available in source form (only) from our download pages at

and mirror sites.

MySQL 5.0.51a is a security hotfix release. We recommend all users of
any previous release in the MySQL 5.0 Community Server branch to upgrade to 5.0.51a as soon as possible. Please see below for details.

Note that not all mirror sites may be up to date at this point in time,
so if you can't find this version on some mirror, please try again later
or choose another download site.

We welcome and appreciate your feedback, bug reports, bug fixes,
patches etc.:

The following section lists the changes from version to version in the
MySQL source code as compared to the last released version of MySQL
Community Server, the MySQL Community Server 5.0.51 release.
It can also be viewed online at

This is a bugfix release for the current production release
family. It replaces MySQL 5.0.51.

Security fixes:

* Three vulnerabilities in yaSSL versions 1.7.5 and earlier were
discovered that could lead to a server crash or execution of
unauthorized code. The exploit requires a server with yaSSL enabled
and TCP/IP connections enabled, but does not require valid MySQL
account credentials. The exploit does not apply to OpenSSL.

The proof-of-concept exploit is freely available on the Internet.
Everyone with a vulnerable MySQL configuration is advised to upgrade


* 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:

* When using a FEDERATED table, the local server can be forced to crash
if the remote server returns a result with fewer columns than
expected. (Bug#29801:
