What is CVE-2013-6461?

The Nokogiri gem versions 1.5.x and 1.6.x are susceptible to Denial of Service attacks due to improper handling of XML entities. The vulnerability arises when Nokogiri fails to apply limits while parsing XML, which can be exploited to exhaust system resources, rendering the affected application unresponsive.
