<description>
<p>
mu-b discovered a NULL pointer dereference in item_cmpfunc.cc when
processing certain types of SQL requests. Sec Consult also discovered
another NULL pointer dereference when sorting certain types of queries
on the database metadata.
</p>
</description>
<impact type="normal">
<p>
In both cases, a remote attacker could send a specially crafted SQL
request to the server, possibly resulting in a server crash. Note that
the attacker needs the ability to execute SELECT queries.
</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 --ask --oneshot --verbose "&gt;=dev-db/mysql-5.0.38"</code>
</resolution>
