[PATCH 5/7] netfilter: nft_nat: insufficient attribute validation

From: Pablo Neira Ayuso <pablo@netfilter.org>
Date: 2014-10-20 08:10:37
Also in: netfilter-devel
Subsystem: netfilter, networking [general], the rest · Maintainers: Pablo Neira Ayuso, Florian Westphal, "David S. Miller", Eric Dumazet, Jakub Kicinski, Paolo Abeni, Linus Torvalds 

We have to validate that we at least get an NFTA_NAT_REG_ADDR_MIN or
NFTA_NFT_REG_PROTO_MIN attribute. Reject the configuration if none
of them are present.
