Vulnerability description

A vulnerability in the packet-processing code of Cisco IOS XR Software for Cisco ASR 9000 Series Aggregation Services Routers (ASR) could allow an unauthenticated, remote attacker to cause a lockup and eventual reload of a network processor chip and the line card that is processing traffic. Only Typhoon-based line cards on Cisco ASR 9000 Series Aggregation Services Routers are affected by this vulnerability.

Risk description

The vulnerability is due to improper processing of packets that are routed via the bridge-group virtual interface (BVI) when any of the following features are configured: Unicast Reverse Path Forwarding (uRPF), policy-based routing (PBR), quality of service (QoS), or access control lists (ACLs). An attacker could exploit this vulnerability by sending IPv4 packets through an affected device that is configured to route them via the BVI interface.
