    Summary: OpenStack Neutron allows remote attackers to bypass an intended ICMPv6-spoofing protection mechanism

    Details: The IPTables firewall in OpenStack Neutron before 7.0.4 and 8.0.0 through 8.1.0 allows remote attackers to bypass an intended ICMPv6-spoofing protection mechanism and consequently cause a denial of service or intercept network traffic via a link-local source address.
