Descriptions

Unbound before 1.3.4 does not properly verify signatures for NSEC3 records, which allows remote attackers to cause secure delegations to be downgraded via DNS spoofing or other DNS-related attacks in conjunction with crafted delegation responses.

Unbound anterior v1.3.4 no comprueba las firmas para registros NSEC3, lo que permite a atacantes remotos causar una delegación de seguridad para ser descargada a través de suplantación de DNS u otros ataques relativos al DNS conjuntamente con respuestas de delegación manipuladas.
