changelog

Drupal 5.21 and 6.15 were released in response to the discovery of security vulnerabilities. Details can be found in the official security advisory:

• SA-CORE-2009-009

To fix the security problem, you can either (1) upgrade Drupal or (2) patch Drupal.

We strongly recommend you do a full upgrade (which is also detailed in the security announcement) as the patches do not contain the additional bug fixes that went into the releases. Applying the patches will leave your site in an unversioned state and confuse the update status module, which will keep reminding you to upgrade to 6.15 or 5.21. Please read the announcement for details on the patch.

If you still prefer to patch Drupal, apply the http://drupal.org/files/sa-core-2009-009/SA-CORE-2009-009-6.14.patch file to your Drupal 6.14 codebase or http://drupal.org/files/sa-core-2009-009/SA-CORE-2009-009-5.20.patch to your Drupal 5.20 codebase.
