Descriptions
An error in handling certain queries can cause an assertion failure when a server is using the nxdomain-redirect feature to cover a zone for which it is also providing authoritative service. A vulnerable server could be intentionally stopped by an attacker if it was using a configuration that met the criteria for the vulnerability and if the attacker could cause it to accept a query that possessed the required attributes. Please note: This vulnerability affects the "nxdomain-redirect" feature, which is one of two methods of handling NXDOMAIN redirection, and is only available in certain versions of BIND. Redirection using zones of type "redirect" is not affected by this vulnerability. Affects BIND 9.9.8-S1 -> 9.9.8-S3, 9.9.9-S1 -> 9.9.9-S6, 9.11.0-9.11.0-P1.
Un error a la hora de manejar ciertas consultas puede provocar un fallo de aserción cuando un servidor emplea la característica nxdomain-redirect para cubrir una zona para la que también está prestando servicios autoritativos. Un servidor vulnerable podría ser detenido de forma intencional por un atacante si está empleando una configuración que cumple los criterios para la vulnerabilidad y si el atacante puede provocar que acepte una consulta que posee los atributos necesarios. Nótese: esta vulnerabilidad afecta a la característica "nxdomain-redirect", que es uno de los dos métodos para gestionar la redirección de NXDOMAIN y solo está disponible en ciertas versiones de BIND. La redirección mediante zonas de tipo "redirect" no se ha visto afectada por esta vulnerabilidad. Afecta a BIND desde la versión 9.9.8-S1 hasta la 9.9.8-S3, desde la versión 9.9.9-S1 hasta la 9.9.9-S6 y a la versión 9.11.0-9.11.0-P1.
