Omschrijving
Cisco heeft kwetsbaarheden verholpen in Cisco IOS XR Software.
De kwetsbaarheden bevinden zich in de wijze waarop Cisco IOS XR Software omgaat met de management interface ACL-verwerking, het installatieproces en de ARP-implementatie. Een kwaadwillende kan deze kwetsbaarheden misbruiken om geconfigureerde toegangscontrolelijsten te omzeilen, niet-ondertekende software te laden of een broadcaststorm te genereren, wat kan leiden tot ongeautoriseerde toegang, code-executie en een Denial-of-Service (DoS) situatie. Dit heeft aanzienlijke gevolgen voor de integriteit en beschikbaarheid van netwerksystemen.
Oplossingen
Cisco heeft updates uitgebracht om de kwetsbaarheden te verhelpen. Zie bijgevoegde referenties voor meer informatie.
