CVE-2011-0530 NBD vulnerability
Title: NBD vulnerability
Summary: An attacker could send crafted input to NBD and cause it to crash or to run
arbitrary programs.
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.
Instructions: After a standard system update you need to restart NBD to make all the
necessary changes.
