Successful exploitation of any of these vulnerabilities could allow an unauthenticated remote attacker to trigger a reload of the embedded services processors (ESP) card or the route processor (RP) card, causing an interruption of services. Repeated exploitation could result in a sustained DoS condition. Note: Cisco IOS Software and Cisco IOS-XR Software are not affected by these vulnerabilities. Cisco has released free software updates that address these vulnerabilities.
