A remote authenticated user can cause denial of service conditions. This issue affects versions prior to MySQL 5.1.48. A remote authenticated user can send a specially crafted ALTER DATABASE command to cause the target server to move a data directory into a new subdirectory, causing the data directory to become unusable. A demonstration exploit request is provided [where "<special>" is "." or ".." or is a sequence that begins with "./" or "../"]: ALTER DATABASE `#mysql50#<special>` UPGRADE DATA DIRECTORY NAME # <a href='http://inj3ct0r.com/'>Inj3ct0r.com</a> [2010-08-03]</pre><script type='text/javascript'>var gaJsHost = (("https:" == document.location.protocol) ?
