Descriptions

resolv.rb in Ruby 1.8.5 and earlier, 1.8.6 before 1.8.6-p287, 1.8.7 before 1.8.7-p72, and 1.9 r18423 and earlier uses sequential transaction IDs and constant source ports for DNS requests, which makes it easier for remote attackers to spoof DNS responses, a different vulnerability than CVE-2008-1447.

resolv.rb en Ruby 1.8.5 y versiones anteriores, 1.8.6 versiones anteriores a 1.8.6-p287, 1.8.7 versiones anteriores a 1.8.7-p72, y 1.9 r18423 y versiones anteriores utiliza transacciones secuenciales de IDs y puertos de origen constante para peticiones DNS, lo cual hace más sencillo para atacantes remotos envenenar respuestas DNS, una vulnerabilidad diferente a CVE-2008-1447.
