View affected systems

Topic

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

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.

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.

Multiple input validation vulnerabilities were discovered in
rubygem-activerecord. A remote attacker could possibly use these flaws to
perform an SQL injection attack against an application using
rubygem-activerecord. (CVE-2012-2661, CVE-2012-2695, CVE-2012-6496,
CVE-2013-0155)

Multiple input validation vulnerabilities were discovered in
rubygem-actionpack. A remote attacker could possibly use these flaws to
perform an SQL injection attack against an application using
rubygem-actionpack and rubygem-activerecord. (CVE-2012-2660, CVE-2012-2694)

Multiple cross-site scripting (XSS) flaws were found in rubygem-actionpack.
A remote attacker could use these flaws to conduct XSS attacks against
users of an application using rubygem-actionpack. (CVE-2012-3463,
CVE-2012-3464, CVE-2012-3465)

A flaw was found in the HTTP digest authentication implementation in
rubygem-actionpack. A remote attacker could use this flaw to cause a
denial of service of an application using rubygem-actionpack and digest
authentication. (CVE-2012-3424)

Users are advised to upgrade to these updated rubygem-actionpack,
rubygem-activesupport, and rubygem-activerecord packages, which resolve
these issues. Katello must be restarted ("service katello restart") for
this update to take effect.

Solution

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