  ND_OPT_DNSSL_INFORMATION option. A remote attacker could exploit this with
  a specially-crafted request and cause the radvd daemon to crash, or
  possibly execute arbitrary code. The default compiler options for affected
  releases should reduce the vulnerability to a denial of service. This issue
  only affected Ubuntu 11.04 and 11.10. (CVE-2011-3601)

  Vasiliy Kulikov discovered that radvd incorrectly filtered interface names
  when creating certain files. A local attacker could exploit this to
  overwrite certain files on the system, bypassing intended permissions.
  (CVE-2011-3602)

  Vasiliy Kulikov discovered that radvd incorrectly handled certain lengths.
  A remote attacker could exploit this to cause the radvd daemon to crash,
  resulting in a denial of service. (CVE-2011-3604)

  Vasiliy Kulikov discovered that radvd incorrectly handled delays when used
  in unicast mode, which is not the default in Ubuntu. If used in unicast
  mode, a remote attacker could cause radvd outages, resulting in a denial of
  service. (CVE-2011-3605)";
