+  <title>MySQL: Multiple vulnerabilities</title>
+  <synopsis>
+    Several vulnerabilities including privilege abuse, Denial of Service, and
+    potentially remote arbitrary code execution have been discovered in MySQL.

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