CVE-2014-8160
Published: 31 December 2014
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.
From the Ubuntu Security Team
A restriction bypass was discovered in iptables when conntrack rules are specified and the conntrack protocol handler module is not loaded into the Linux kernel. This flaw can cause the firewall rules on the system to be bypassed when conntrack rules are used.
