Synopsis: Important: ruby193-rubygem-actionpack security update

Product: Red Hat OpenStack
Advisory URL: https://rhn.redhat.com/errata/RHSA-2014-0008.html

=====================================================================
1. Summary:
Updated ruby193-rubygem-actionpack packages that fix multiple security
issues are now available for Red Hat OpenStack 3.0.
The Red Hat Security Response Team has rated this update as having
important 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.
2. Relevant releases/architectures:
OpenStack 3 - noarch
3. Description:
Ruby on Rails is a model-view-controller (MVC) framework for web
application development. Action Pack implements the controller and the
view components.
A flaw was found in the way Ruby on Rails performed JSON parameter parsing.
An application using a third party library, which uses the Rack::Request
interface, or custom Rack middleware could bypass the protection
implemented to fix the CVE-2013-0155 vulnerability, causing the application
to receive unsafe parameters and become vulnerable to CVE-2013-0155.
(CVE-2013-6417)
It was discovered that the internationalization component of Ruby on Rails
could, under certain circumstances, return a fallback HTML string that
contained user input. A remote attacker could possibly use this flaw to
perform a reflective cross-site scripting (XSS) attack by providing a
specially crafted input to an application using the aforementioned
component. (CVE-2013-4491)
A denial of service flaw was found in the header handling component of
Action View. A remote attacker could send strings in specially crafted
headers that would be cached indefinitely, which would result in all
available system memory eventually being consumed. (CVE-2013-6414)
It was found that the number_to_currency Action View helper did not
properly escape the unit parameter. An attacker could use this flaw to
perform a cross-site scripting (XSS) attack on an application that uses
data submitted by a user in the unit parameter. (CVE-2013-6415)
Users of Red Hat OpenStack 3.0 are advised to upgrade to these updated
packages, which correct these issues.
