Red Hat Security Advisory 2013-0670-01 - The Django web framework is used by Horizon, the OpenStack Dashboard, which is a web interface for managing OpenStack services. A denial of service flaw was found in the Extensible Markup Language parser used by Django. A remote attacker could use this flaw to send a specially-crafted request to an Horizon API, causing Horizon to consume an excessive amount of CPU and memory. A flaw was found in the XML parser used by Django. If a remote attacker sent a specially-crafted request to an Horizon API, it could cause Horizon to connect to external entities, causing a large amount of system load, or allow an attacker to read files on the Horizon server that are accessible to the user running Horizon.

An attacker could exploit this to generate and display arbitrary URLs to users. Although this issue had been previously addressed in USN-1632-1, this update adds additional hardening measures to host header validation. This update also adds a new ALLOWED_HOSTS setting that can be set to a list of acceptable values for headers. Orange Tsai discovered that Django incorrectly performed permission checks when displaying the history view in the admin interface. An administrator could use this flaw to view the history of any object, regardless of intended permissions. Various other issues were also addressed.
