Red Hat OpenShift: RHSA-2013:0701-01 Moderate: Ruby JSON RDoc Issues

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.
