tag_insight = "A vulnerability has been found and corrected in ruby:

  Ruby (aka CRuby) before 1.8.7-p357 computes hash values without
  restricting the ability to trigger hash collisions predictably,
  which allows context-dependent attackers to cause a denial of service
  (CPU consumption) via crafted input to an application that maintains
  a hash table (CVE-2011-4815).

  The updated packages have been patched to correct this issue.";
