tag_insight = "Ruby is an interpreted scripting language for quick and easy
  object-oriented programming.

  Multiple integer overflows leading to a heap overflow were discovered in
  the array- and string-handling code used by Ruby. An attacker could use
  these flaws to crash a Ruby application or, possibly, execute arbitrary
  code with the privileges of the Ruby application using untrusted inputs in
  array or string operations. (CVE-2008-2376, CVE-2008-2663, CVE-2008-2725,
  CVE-2008-2726)
  
  It was discovered that Ruby used the alloca() memory allocation function in
  the format (%) method of the String class without properly restricting
  maximum string length. An attacker could use this flaw to crash a Ruby
  application or, possibly, execute arbitrary code with the privileges of the
  Ruby application using long, untrusted strings as format strings.
  (CVE-2008-2664)
  
  Red Hat would like to thank Drew Yao of the Apple Product Security team for
  reporting these issues.
  
  A flaw was discovered in the way Ruby's CGI module handles certain HTTP
  requests. A remote attacker could send a specially crafted request and
  cause the Ruby CGI script to enter an infinite loop, possibly causing a
  denial of service. (CVE-2006-6303)
  
  Users of Ruby should upgrade to these updated packages, which contain a
  backported patches to resolve these issues.";
