SYNTHESIS OF THE VULNERABILITY
An attacker can send crafted BGP packets to a Cisco IOS or IOS XE
equipment, in order to trigger a denial of service.
Impacted products: IOS by Cisco, IOS XE Cisco, Cisco Router.
Severity: 2/4.
Creation date: 18/07/2016.
DESCRIPTION OF THE VULNERABILITY
The Cisco IOS or IOS XE product offers the BGP protocol to
exchange network routes with neighbour routers.
However, in certain cases an implementation error generates a
fatal error via BGP.
An attacker can therefore send crafted BGP packets to a Cisco IOS
or IOS XE equipment, in order to trigger a denial of service.
