    nbd vulnerability
    A security issue affects these releases of Ubuntu and its derivatives:
    - Ubuntu 10.10
    - Ubuntu 10.04 LTS
    - Ubuntu 8.04 LTS
    An attacker could send crafted input to NBD and cause it to crash or to run
    arbitrary programs.
    Software Description:
    - nbd: Network Block Device protocol
    It was discovered that NBD incorrectly handled certain long requests. A
    remote attacker could use this flaw to cause NBD to crash, resulting in
    a denial of service, or possibly execute arbitrary code.
    Update instructions:
    The problem can be corrected by updating your system to the following
    package versions:
    Ubuntu 10.10:
      nbd-server                      1:2.9.14-2ubuntu1.10.10.1
    Ubuntu 10.04 LTS:
      nbd-server                      1:2.9.14-2ubuntu1.10.04.1
    Ubuntu 8.04 LTS:
      nbd-server                      1:2.9.9-1ubuntu1.1
    After a standard system update you need to restart NBD to make all the
    necessary changes.
