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

  It was discovered that Ruby's REXML library did not properly restrict XML
  entity expansion. An attacker could use this flaw to cause a denial of
  service by tricking a Ruby application using REXML to read text nodes from
  specially-crafted XML content, which will result in REXML consuming large
  amounts of system memory. (CVE-2013-1821)

  All users of Ruby are advised to upgrade to these updated packages, which
  contain backported patches to resolve this issue.";
