Risk: High
Recent versions of Cisco IOS Software contain two remote denial of service (DoS) vulnerabilities when handling specific Border Gateway Protocol (BGP) updates.
The first vulnerability could cause an affected device to reload when processing a BGP update that contains autonomous system (AS) path segments made up of more than one thousand autonomous systems.
The second vulnerability could cause an affected device to reload when it processes a malformed BGP update that has been crafted to trigger the issue.
