(RHSA-2016:1271) Important: python-django-horizon security and bug fix update

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

Security Fix(es):

• A DOM-based, cross-site scripting vulnerability was found in the OpenStack dashboard, where user input was not filtered correctly. An authenticated dashboard user could exploit the flaw by injecting an AngularJS template into a dashboard form (for example, using an image’s description), triggering the vulnerability when another user browsed the affected page. As a result, this flaw could result in user accounts being compromised (for example, user-access credentials being stolen). (CVE-2016-4428)

Red Hat would like to thank the OpenStack project for reporting this issue. Upstream acknowledges Beth Lancaster (Virginia Tech) and Brandon Sawyers (Virginia Tech) as the original reporters.

Bug Fix(es):

• Having two security groups with the same name previously resulted in not being able to launch an instance if it used one of these groups. This bug has been fixed. (BZ#1293232)

• Previously, under some circumstances, the hypervisor list was not alphabetized. In this update, the sort attribute has been changed, and badly sorted lists no longer occur. (BZ#1238092)
