<p>
MySQL is a popular open-source, multi-threaded, multi-user SQL database
server.

<description>
<p>
The following vulnerabilities were found and fixed in MySQL:
</p>
<p>
Oleksandr Byelkin found that ALTER TABLE ... RENAME checks CREATE/INSERT
rights of the old table instead of the new one (CAN-2004-0835). Another
privilege checking bug allowed users to grant rights on a database they had
no rights on.
</p>
<p>
Dean Ellis found a defect where multiple threads ALTERing the MERGE tables
to change the UNION could cause the server to crash (CAN-2004-0837).
Another crash was found in MATCH ... AGAINST() queries with missing closing
double quote.
</p>
<p>
Finally, a buffer overrun in the mysql_real_connect function was found by
Lukasz Wojtow (CAN-2004-0836).
</p>
</description>
<impact type="high">
<p>
The privilege checking issues could be used by remote users to bypass their
rights on databases. The two crashes issues could be exploited by a remote
user to perform a Denial of Service attack on MySQL server. The buffer
overrun issue could also be exploited as a Denial of Service attack, and
may allow to execute arbitrary code with the rights of the MySQL daemon
(typically, the "mysql" user).
</p>
</impact>
<workaround>
<p>
There is no known workaround at this time.
</p>
</workaround>
<resolution>
<p>
All MySQL users should upgrade to the latest version:
</p>
<code>
# emerge sync
# emerge -pv ">=dev-db/mysql-4.0.21"
# emerge ">=dev-db/mysql-4.0.21"</code>
</resolution>
