Synopsis

Moderate: python-django-horizon security and bug fix update

Type/Severity

Security Advisory: Moderate

Topic

Updated python-django-horizon packages that fix multiple security issues
are now available for Red Hat Enterprise Linux OpenStack Platform 6.0.

Red Hat Product Security has rated this update as having Moderate security
impact. Common Vulnerability Scoring System (CVSS) base scores, which give
detailed severity ratings, are available for each vulnerability from the
CVE links in the References section.

Description

OpenStack Dashboard (Horizon) provides administrators and users with a
graphical interface to access, provision, and automate cloud-based
resources.

Two security issues were discovered in the Horizon dashboard and are
addressed in this update:

• A cross-site scripting (XSS) flaw was found in the Horizon Orchestration
  dashboard. An attacker able to trick a Horizon user into using a malicious
  template during the stack creation could use this flaw to perform an XSS
  attack on that user. (CVE-2015-3219)
  

Red Hat would like to thank the OpenStack Project for reporting the
CVE-2015-3219 issue. Upstream acknowledges Nikita Konovalov from Mirantis
as the original reporter of CVE-2015-3219.

• A flaw was discovered in the Horizon metadata dashboard whereby
  potentially untrusted data was displayed from Glance images, Nova flavors,
  or host aggregates without correct clean up. An attacker could use this
  flaw to conduct an XSS attack.(CVE-2015-3988)
  

Additionally, the following non-security issues are addressed:

• It was impossible to associate a floating IP address to a port for an
  instance. This occurred if the gateway router was not in the same tenant as
  the instance but was attached to a network shared across tenants because
  only ports within the tenant were used to find reachable gateway routers.
  (BZ#1187992)
  
• If two or more regions were configured in Horizon, then the User, Help,
  and Current Project links would no longer work and the region selector
  was in the wrong location in the UI. (BZ#1189887)
  
• A load balancer monitor was erroneously displayed as associated with
  every tenant in every pool. The load balancer monitor was not actually
  associated with any tenants, but the improper display prevented users
  from using the Horizon dashboard to create a tenant association.
  (BZ#1196249)
  
• When logging into the Horizon dashboard, Horizon sends a query to Nova to
  update usage statistics. One of the calls would erroneously query deleted
  virtual machines; if there were thousands of deleted virtual machines, the
  CPU usage for Nova would spike and the Nova process could crash.
  (BZ#1243301)
  
• The network profile was not supported by Cisco N1KV ML2 drivers. This
  profile has been removed to maintain Horizon compatibility with the Cisco
  driver. (BZ#1246690)
  
• A neutron attribute extension was renamed from profile_id to profile for
  networks and ports. This caused create operations for networks and ports to
  fail from the dashboard since the dashboard was still using the attribute
  name n1kv:profile_id rather than n1kv:profile.(BZ#1248367)
  
• If a virtual machine instance failed to launch, then the stale port
  assignments were left in the configuration rather than being cleaned up.
  (BZ#1249228)
  

All python-django-horizon users are advised to upgrade to these updated
packages, which correct these issues.
