Summary

Cisco IOS XR Software is affected by a denial of service (DoS) vulnerability 
that could allow an authenticated, local attacker to trigger a reload of the
affected device by locally generating certain Internet Control Message 
Protocol (ICMP) messages.

The vulnerability is due to a combination of Silicon Packet Processor (SPP)
buffer corruption and a mutex issue when an extended ping with timeout=0 and
a large packet size is terminated with Control-C. An attacker could exploit
this vulnerability by sending large ICMP packets from an affected device.

What Is a Cisco Security Notice?

The Cisco Product Security Incident Response Team (PSIRT) publishes Cisco 
Security Notices to inform customers of low- to mid-level severity security

these issues should contact their normal support channels. Free software 
updates will not be provided for issues that are disclosed through a Cisco

organizations to ensure that any applied workaround or fix is the most
appropriate in the intended network before it is deployed.
