URGENT: FCKeditor remote file upload vulnerability

There's a vulnerability allowing to upload files in the FCKeditor
version included in EGroupware 1.6.001 and EPL 9.1.

See http://www.securityfocus.com/archive/1/504721/30/0/threaded

We are working on a new security update (EGroupware 1.6.002). In the
meantime, please implemented the mitigation instructions of the above link.

In short delete the following directories or make them via unix
permissions inaccessible:

- phpgwapi/js/fckeditor/editor/filemanager/connectors (file upload)
- phpgwapi/js/fckeditor/_samples (XXS)

This will render fileupload and file/image browser unusable! Also check
if there have been files uploaded to your system (typically script to
eg. excute shell commands).
