Synopsis

The remote Red Hat host is missing one or more security updates.

Description

Updated ruby193-ruby, rubygem-json and rubygem-rdoc packages that fix two security issues are now available for Red Hat OpenShift Enterprise 1.1.3.

The Red Hat Security Response Team has rated this update as having moderate 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.

Ruby is an extensible, interpreted, object-oriented, scripting language. It has features to process text files and to do system management tasks.

A flaw in rubygem-json and ruby193-rubygem-json allowed remote attacks by creating different types of malicious objects. For example, it could initiate a denial of service attack through resource consumption by using a JSON document to create arbitrary Ruby symbols, which were never garbage collected. It could also be exploited to create internal objects which could allow a SQL injection attack. (CVE-2013-0269)

It was found that documentation created by rubygem-rdoc and ruby193-rubygem-rdoc was vulnerable to a cross-site scripting (XSS) attack. If such documentation was accessible over a network, and a remote attacker could trick a user into visiting a specially crafted URL, it would lead to arbitrary web script execution in the context of the user's session. As rubygem-rdoc and ruby193-rubygem-rdoc are used for creating documentation for Ruby source files (such as classes, modules, and so on), it is not a common scenario to make such documentation accessible over the network. (CVE-2013-0256)

Red Hat would like to thank Ruby on Rails upstream for reporting CVE-2013-0269, and Eric Hodel of RDoc upstream for reporting CVE-2013-0256. Upstream acknowledges Thomas Hollstegge of Zweitag and Ben Murphy as the original reporters of CVE-2013-0269, and Evgeny Ermakov as the original reporter of CVE-2013-0256.

Users of Red Hat OpenShift Enterprise 1.1.3 are advised to upgrade to these updated packages, which correct these issues.

Solution
