Patch Update for IP.Board 3.0.5

We have been working over the past week with Aoyagi Ritsuka on hardening the code for several BBCode tags. I have attached a new zip in the original post for IP.Board 3.0.5 which contains the original fix plus improvements in security in other tags which will prevent future exploits from being successful.

This patch also includes a fix for a minor issue with hidden redirect scripts being able to remove user's avatars and/or photos.

As usual, please download the zip file, expand and upload the files over the copies on your server. No further action is required.

The main download zip has been updated at the time of this post.

Note: Zip file was updated at 16:30 GMT to fix a platform specific issue.
