CVE-2011-1076
Published: 4 March 2011
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.
From the Ubuntu Security Team
It was discovered that the key-based DNS resolver did not correctly handle certain error states. A local attacker could exploit this to crash the system, leading to a denial of service.
