Il primo problema critico si manifesta su dispositivi che supportano tunnel IPv4, mentre il secondo su versioni rilasciate prima del 04.06.2009 che supportano IPv6. Un'altra vulnerabilit\u00e0 critica (CVSS 9) \u00e8 presente nel resolver DNS (CVE-2020-11901) e consente l'esecuzione di codice tramite l'invio di una richiesta DNS opportunamente formattata (il problema \u00e8 stato utilizzato per dimostrare l'attacco a Schneider Electric APC UPS e si manifesta su dispositivi con supporto DNS).<\/p>\n<p>Altre vulnerabilit\u00e0 CVE-2020-11898, CVE-2020-11899, CVE-2020-11902, CVE-2020-11903, CVE-2020-11905 consentono di ottenere contenuti delle aree di memoria del sistema inviando pacchetti IPv4\/ICMPv4, IPv6OverIPv4, DHCP, DHCPv6 opportunamente formattati.

dispositivi sono rimasti senza supporto o sono difficili da aggiornare), si raccomanda agli amministratori di isolare i dispositivi problematici e configurare nei sistemi di ispezione dei pacchetti, nei firewall o nei router la normalizzazione o il blocco dei pacchetti frammentati, bloccare i tunnel IP (IPv6-in-IPv4 e IP-in-IP), disabilitare il \"source routing\", attivare l'ispezione delle opzioni non corrette nei pacchetti TCP, bloccare i messaggi di controllo ICMP non utilizzati (MTU Update e Address Mask), vietare il multicast IPv6 e reindirizzare le query DNS a un server DNS
