More information:

Two vulnerabilities were reported in BIND, a DNS server.

• CVE-2016-2775

  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-2016-2776

  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.

For the stable distribution (jessie), these problems have been fixed in version 1:9.9.5.dfsg-9+deb8u7.

We recommend that you upgrade your bind9 packages.
