An attacker could exploit this vulnerability by sending a crafted IPv6 packet that is encapsulated within an MPLS frame to an MPLS-enabled interface of the targeted device. A successful exploit could allow the attacker to cause a denial of service (DoS) condition.\r\n\r Note: The IPv6 packet can be generated multiple hops away from the targeted device and then encapsulated within MPLS. The DoS condition may occur when the NX-OS device processes the packet.", "affected": [ { "vendor": "Cisco", "product": "Cisco NX-OS Software", "versions": [ { "version": "6.0(2)A3(1)", "status":
