  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.");
