Summary
A vulnerability in Internet Control Message Protocol version 6 (ICMPv6)
processing of Cisco IOS XR Software could allow an unauthenticated, adjacent
attacker to affect IPv4 and IPv6 traffic passing through an affected device.
The vulnerability is due to how ICMPv6 redirect packets are throttled by an
affected device. An attacker could exploit this vulnerability by sending
crafted ICMPv6 redirect packets to an affected device. An exploit could allow
the attacker to cause all or most of the IPv4 and IPv6 traffic to fail while
being processed on an affected device.
