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.
