Open vSwitch provides standard network bridging functions and support for the OpenFlow protocol for remote per-flow control of traffic. Security Fixes: A flaw was found in openvswitch OVS. When processing an IP packet with protocol 0, OVS will install the datapath flow without the action modifyin...

openvswitch: ip proto 0 triggers incorrect handling

A flaw was found in openvswitch OVS. When processing an IP packet with protocol 0, OVS will install the datapath flow without the action modifying the IP header. This issue results for both kernel and userspace datapath in installing a datapath flow matching all IP protocols nwproto is wildcarded...

A flaw was found in openvswitch (OVS). When processing an IP packet with protocol 0 OVS will install the datapath flow without the action modifying the IP header. This issue results (for both kernel and userspace datapath) in installing a datapath flow matching all IP protocols (nw_proto is wildcarded) for this flow but with an incorrect action possibly causing incorrect handling of other IP packets with a != 0 IP protocol that matches this dp flow.
