Synopsis:          Critical: Ruby on Rails security update
Advisory ID:       RHSA-2013:0155-01
Product:           Red Hat CloudForms
Advisory URL:      https://rhn.redhat.com/errata/RHSA-2013-0155.html
Issue date:        2013-01-10

=====================================================================

1. Summary:

Updated rubygem-actionpack, rubygem-activesupport, and rubygem-activerecord
packages that fix multiple security issues are now available for Red Hat
CloudForms.

The Red Hat Security Response Team has rated this update as having critical
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:

Cloud Engine for RHEL 6 Server - noarch
System Engine for RHEL 6 Server - 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. Active Record implements object-relational mapping for
accessing database entries using objects. Active Support provides support
and utility classes used by the Ruby on Rails framework.

Multiple flaws were found in the way Ruby on Rails performed XML parameter
parsing in HTTP requests. A remote attacker could use these flaws to
execute arbitrary code with the privileges of a Ruby on Rails application,
perform SQL injection attacks, or bypass the authentication using a
specially-created HTTP request. (CVE-2013-0156)

Red Hat is aware that a public exploit for the CVE-2013-0156 issues is
available that allows remote code execution in applications using Ruby on
Rails.

A flaw was found in the way Ruby on Rails performed JSON parameter parsing.
If a Ruby on Rails application passed JSON parameters to Active Record, it
could result in the generation of unexpected SQL queries. A remote attacker
could possibly use this flaw to manipulate SQL queries executed by the
application. (CVE-2013-0155)

A flaw was found in the way rubygem-activerecord dynamic finders extracted
options from method parameters. A remote attacker could possibly use this
flaw to perform SQL injection attacks against applications using the Active
Record dynamic finder methods. (CVE-2012-6496)

Users are advised to upgrade to these updated rubygem-actionpack,
rubygem-activesupport, and rubygem-activerecord packages, which resolve
these issues. Users of CloudForms Cloud Engine must run "aeolus-services
restart" and users of CloudForms System Engine must run "katello-service
restart" for this update to take effect.

4. Solution:

Before applying this update, make sure all previously-released errata
relevant to your system have been applied.
