 		<ul>
 			<li>An improvement was made to the MySQL and MySQLi drivers to prevent exposing a potential vector for SQL injection on sites using multi-byte character sets in the database client connection.  <p>An incompatibility in PHP versions &lt; 5.2.3 and MySQL &lt; 5.0.7 with <em>mysql_set_charset()</em> creates a situation where using multi-byte  character sets on these environments may potentially expose a SQL injection attack vector.  Latin-1, UTF-8, and other "low ASCII" character sets are unaffected on all environments.</p>  <p class="critical">If you are running or considering running a multi-byte character set for your database connection, please pay close attention to the server environment you are deploying on to ensure you are not vulnerable.</p></li>
