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

Publicada: 14.05.2022
Actualizado: 11.10.2026 13:17

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.
