high Nessus Plugin ID 64281

Language:

Synopsis

The remote Red Hat host is missing a security update.

Description

An updated rubygem-activesupport package that fixes one security issue is now available for Red Hat Subscription Asset Manager.

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.

Users of Red Hat Subscription Asset Manager are advised to upgrade to this updated package, which resolves this issue. Katello must be restarted ('service katello restart') for this update to take effect.

Solution

Update the affected rubygem-activesupport package.
