A vulnerability was identified in Cisco Internet Operating System (IOS), which could be exploited by attackers to execute arbitrary commands or cause a denial of service. This flaw is due to a heap overflow error when processing specially crafted IPv6 packets, which could be exploited by an unauthenticated attacker to execute arbitrary code and compromise a vulnerable device.
Note : The packet must be sent from a local network segment. Only devices that have been explicitly configured to process IPv6 traffic are affected.
