Details

An updated rubygem-activesupport package that fixes one security issue is
now available for Red Hat OpenShift Enterprise 1.0.

The Red Hat Security Response Team has rated this update as having critical
security impact. A Common Vulnerability Scoring System (CVSS) base score,
which gives a detailed severity rating, is available from the CVE link in
the References section.

Ruby on Rails is a model–view–controller (MVC) framework for web
application development. Active Support provides support and utility
classes used by the Ruby on Rails framework.

A flaw was found in the way Active Support performed the parsing of JSON
requests by translating them to YAML. A remote attacker could use this flaw
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 JSON request. (CVE-2013-0333)

Red Hat would like to thank Ruby on Rails upstream for reporting this
issue. Upstream acknowledges Lawrence Pit of Mirror42 as the original
reporter.

All users of Red Hat OpenShift Enterprise are advised to upgrade to this
updated package, which resolves this issue. For Red Hat OpenShift
Enterprise administrators, the openshift-broker and openshift-console
services must be restarted for this update to take effect. Users of
OpenShift are advised to update their own applications that are running
Ruby on Rails.
