Is there a security problem with Timthumb?
The latest version of the theme uses TimThumb v2 which was created in response to the TimThumb v1.x vulnerability issue reported in August 2011. This new version corrects the security problem so there is nothing to worry about.
If you’re using Unite v2.0.2 or earlier you can update the TimThumb file by downloading the latest version here:http://timthumb.googlecode.com/svn/trunk/timthumb.php
(right click, save link as…, “timthumb.php”)
After downloading the new file go to your theme folder and replace the old file “
includes/timthumb.php” with the new one and you’re done.
