The lwresd component in BIND (which is not enabled by default) could crash while processing an overlong request name. This could lead to a denial of service (CVE-2016-2775).
A crafted query could crash the BIND name server daemon, leading to a denial of service. All server roles (authoritative, recursive and forwarding) in default configurations are affected (CVE-2016-2776).
A conflict between the bind and bind-doc packages has also been fixed (mga#10880).
