Advisory Weakness Curation

Ruby vulnerable to denial of service When reading text nodes from an XML document, the REXML parser can be coerced in to allocating extremely large string objects which can consume all of the memory on a machine, causing a denial of service. Jruby resolves this bug in version 1.7.3 as noted in https://www.jruby.org/2013/02/21/jruby-1-7-3.html

Entity expansion DoS vulnerability in REXML `lib/rexml/text.rb` in the REXML parser allows remote attackers to cause a denial of service (memory consumption and crash) via crafted text nodes in an XML document, aka an XML Entity Expansion (XEE) attack.
