REDHAT-BUG-630687: XSS
Moritz Naumann reported: [1] http://seclists.org/fulldisclosure/2010/Sep/82
a deficiency in the way Horde framework sanitized user-provided 'subdir' parameter, when composing final path to the image file. A remote, unauthenticated user could use this flaw to conduct cross-site scripting attacks (execute arbitrary HTML or scripting code) by providing a specially-crafted URL to the running Horde framework instance.
