Feiten: Cisco heeft meerdere kwetsbaarheden verholpen in Cisco IOS XE Software.
Interpretaties: De kwetsbaarheden zijn intern door Cisco's engineering teams ontdekt tijdens beveiligingsreviews. Deze kwetsbaarheden zijn van invloed op Cisco IOS XE-software wanneer deze in autonome modus of controllermodus wordt uitgevoerd, ongeacht de apparaatconfiguratie. De geïdentificeerde problemen betreffen onder andere onjuiste access control, buffer management fouten, onjuiste resource control en onjuiste input validatie.
Oplossingen: Cisco heeft software hardening updates uitgebracht om de kwetsbaarheden te verhelpen. Zie bijgevoegde referenties voor meer informatie.
