Hi to all!
After I updated my Drupal website from 7.23 to 7.25 I'm getting this

Public files directory	Not fully protected
See http://drupal.org/SA-CORE-2013-003 for information about the recommended .htaccess file which should be added to the sites/default/files directory to help protect against arbitrary code execution.

Temporary files directory	Not fully protected
See http://drupal.org/SA-CORE-2013-003 for information about the recommended .htaccess file which should be added to the /tmp directory to help protect against arbitrary code execution.

On the https://drupal.org/SA-CORE-2013-003 it said under Solution "... upgrade to Drupal core 7.24." In may case it would be downgrade, right?

What should I do?

Thanks for any help,
Afan
