CVE-2014-8160: Canonical Ubuntu Linux

Medium severity, CVSS 5.0. EPSS: 5.5% chance of exploitation in the next 30 days.

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.
