An XSS vulnerability was identified in Amadou theme's themes_links() function in the template.php file, which was fixed in the theme_links() function in Drupal 6.3 as noted in (SA-2008-044 http://drupal.org/node/280571).
This release fixes that security issue and should be applied to all Drupal 6 websites running Amadou theme.
The current 6.x-1.x-dev release also contains this fix.
