Descriptions

net/dns_resolver/dns_key.c in the Linux kernel before 2.6.38 allows remote DNS servers to cause a denial of service (NULL pointer dereference and OOPS) by not providing a valid response to a DNS query, as demonstrated by an erroneous grand.centrall.org query, which triggers improper handling of error data within a DNS resolver key.

net/dns_resolver/dns_key.c del kernel de Linux en versiones anteriores a la 2.6.38 permite a servidores DNS remotos provocar una denegación de servicio (resolución de puntero NULL y OOPS) no proporcionando una respuesta válida a una petición DNS, como se ha demostrado por una petición errónea a grand.centrall.org, lo que provoca un manejo erróneo de datos de error dentro una "DNS resolver key".
