net/netfilter/nf_conntrack_proto_generic.c in the Linux kernel before 3.18 generates incorrect conntrack entries during handling of certain iptables rule sets for the SCTP, DCCP, GRE, and UDP-Lite protocols, which allows remote attackers to bypass intended access restrictions via packets with disallowed port numbers.

This was fixed for JollaC / aquafish in SFOS 2.0.4 but jolla1 is still vulnerable in SFOS .

Patch and kernel-3.2-Patch are identical, so kernel-3.4-adaptation-sbj should see the same fix.

File affected: kernel-adaptation-sbj- lines 15-19

@jovirkku this should have a "tracked by jolla" label
