and released under the GPL, which is as old as or older than version 0.7.4.

The remote version of this software is affected by a SQL injection
attacks in the script 'rss.php'. This issue is due to a failure 
of the application to properly sanitize user-supplied input.

An attacker may use these flaws to execute arbitrary PHP code on this
host or to take the control of the remote database.";
