The udp6_ufo_fragment function in net/ipv6/udp_offload.c in the Linux
kernel through 3.12, when UDP Fragmentation Offload (UFO) is enabled, does
not properly perform a certain size comparison before inserting a fragment
header, which allows remote attackers to cause a denial of service (panic)
via a large IPv6 UDP packet, as demonstrated by use of the Token Bucket
Filter (TBF) queueing discipline.
