The BPF_S_ANC_NLATTR_NEST extension implementation in the sk_run_filter
function in net/core/filter.c in the Linux kernel through 3.14.3 uses the
reverse order in a certain subtraction, which allows local users to cause a
denial of service (over-read and system crash) via crafted BPF
instructions. NOTE: the affected code was moved to the
__skb_get_nlattr_nest function before the vulnerability was announced.
