MySQL is a popular open-source, multi-threaded, multi-user SQL database

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).
|
||
|
|

<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>
|
||
|
