Summary
=======

Cisco IOS XR Software contains a vulnerability when handling crafted
packets that may result in a denial of service condition. The
vulnerability only exists on Cisco 9000 Series Aggregation Services
Routers (ASR) Route Switch Processor (RSP-4G and RSP-8G), Route Switch
Processor 440 (RSP440), and Cisco Carrier Routing System (CRS)
Performance Route Processor (PRP). The vulnerability is a result of
improper handling of crafted packets and could cause the route
processor, which processes the packets, to be unable to transmit
packets to the fabric.

Cisco has released free software updates that address this vulnerability.
