"Dan Luther discovered that Bind incorrectly handled zero length rdata
fields. A remote attacker could use this flaw to cause Bind to crash
or behave erratically, resulting in a denial of service.
(CVE-2012-1667)

It was discovered that Bind incorrectly handled revoked domain names.
A remote attacker could use this flaw to cause malicious domain names
to be continuously resolvable even after they have been revoked.
(CVE-2012-1033).

description block directly from the Ubuntu security advisory. Tenable
has attempted to automatically clean and format it as much as possible
