• 6.4.2 (Available Oct 30, 2017) – All products listed above
  • Please note that four products have fixes for the most severe KRACK vulnerabilities, but still have issues with a group key replay.
    • IBR1100, IBR600, IBR600B, MBR1200B
    • All vulnerability tests pass except for a subset related to a vendor group key replay issue, which will be fixed in a follow-up release.  This specifically affects multicast and broadcast traffic, which is rare.  SSDP (UPnP), IPTV, and Apple Bonjour are examples of multicast and broadcast traffic.  Unicast traffic, which generally accounts for much of secure traffic in the system, has been fixed.
