kernel: netfilter: missing bounds check in ipt_entry structure

A security flaw was found in the Linux kernel in the marksourcechains function in "net/ipv4/netfilter/iptables.c". It is possible for a user-supplied "iptentry" structure to have a large "nextoffset" field. This field is not bounds checked prior to writing to a counter value at the supplied offse...
