Certain – alas, typical – configurations of Apache allow execution of
carefully named arbitrary scripts in the files directory. Drupal now will
attempt to automatically create a .htaccess file in your "files" directory
to protect you.
All Drupal versions before 4.6.7 and also Drupal 4.7.0.
If you are running Drupal 4.6.x then upgrade to Drupal 4.6.7.
If you are running Drupal 4.7.0 then upgrade to Drupal 4.7.1.
Make sure you have a .htaccess in your "files" dir and it contains this line:
SetHandler This_is_a_Drupal_security_line_do_not_remove
The security contact for Drupal can be reached at [email protected]
or using the form at http://drupal.org/contact.
More information is available from http://drupal.org/security or from
our security RSS feed http://drupal.org/security/rss.xml.
