It was discovered that Bind incorrectly handled certain bad signatures if multiple trust anchors existed for a single zone. A remote attacker could use this flaw to cause Bind to stop responding, resulting in a denial of service. This issue only affected Ubuntu 8.04 LTS and 10.04 LTS. (CVE-2010-3762)

Frank Kloeker and Michael Sinatra discovered that Bind incorrectly handled certain very large RRSIG RRsets included in negative responses. A remote attacker could use this flaw to cause Bind to stop responding, resulting in a denial of service. (CVE-2011-1910).
