** Description changed:

- memory corruption with UDP_CORK and UFO
+ The Linux kernel before 3.12, when UDP Fragmentation Offload (UFO) is
+ enabled, does not properly initialize certain data structures, which
+ allows local users to cause a denial of service (memory corruption and
+ system crash) or possibly gain privileges via a crafted application that
+ uses the UDP_CORK option in a setsockopt system call and sends both
+ short and long packets, related to the ip_ufo_append_data function in
+ net/ipv4/ip_output.c and the ip6_ufo_append_data function in
+ net/ipv6/ip6_output.c.
