Details

It was discovered that Bind would incorrectly cache bogus NXDOMAIN
responses. When DNSSEC validation is in use, a remote attacker could
exploit this to cause a denial of service, and possibly poison DNS caches.
(CVE-2010-0097)

USN-865-1 provided updated Bind packages to fix a security vulnerability.
The upstream security patch to fix CVE-2009-4022 was incomplete and
CVE-2010-0290 was assigned to the issue. This update corrects the problem.
Original advisory details:

Michael Sinatra discovered that Bind did not correctly validate certain
records added to its cache. When DNSSEC validation is in use, a remote
attacker could exploit this to spoof DNS entries and poison DNS caches.
Among other things, this could lead to misdirected email and web traffic.
