WordPress 2.8.5: Hardening Release
Posted October 20, 2009 by Peter Westwood
As you know over the past couple of months we have been working on the new features for WordPress 2.9. We have also been working on trying to make WordPress as secure as possible and during this process we have identified a number of security hardening changes that we thought we worth back-porting to the 2.8 branch so as to get these improvements out there and making all your sites as secure as possible.
The headline changes in this release are:
- A fix for the Trackback Denial-of-Service attack that is currently being seen.
- Removal of areas within the code where php code in variables was evaluated.
- Switched the file upload functionality to be whitelisted for all users including Admins.
- Retiring of the two importers of Tag data from old plugins.
We would recommend that all sites are upgraded to this new version of WordPress so as to ensure that you have the best available protection.
If you think your site may have been hit by one of the recent exploits and you would like to make sure that you have cleared out all traces of the exploit then we would recommend that you take a look at the WordPress Exploit Scanner. This is a plugin which searches the files on your website, and the posts and comments tables of your database for anything suspicious. It also examines your list of active plugins for unusual filenames.
