The vulnerability allows a remote attacker to cause DoS condition on the target system.
The weakness exists in the Border Gateway Protocol (BGP) over an Ethernet Virtual Private Network (EVPN) for Cisco IOS XE Software due to changes in the implementation of the BGP MPLS-Based Ethernet VPN RFC (RFC 7432) draft. A remote attacker can send a specially crafted BGP Inclusive Multicast Ethernet Tag Route or BGP EVPN MAC/IP Advertisement Route update packet, corrupt the BGP routing table and cause the device to reload.
Successful exploitation of the vulnerability results in denial of service.
Update to version 16.3 or later.
