DESCRIPTION:
Two vulnerabilities have been reported in Cisco IOS, which can be

be exploited to cause a crash via specially crafted packets.
2) An error when processing ICMPv6 packets with an expired MPLS TTL
can be exploited to cause a crash.
Successful exploitation requires the device to be configured for
MPLS.
