Summary

Open vSwitch provides standard network bridging functions and support for the OpenFlow protocol for remote per-flow control of traffic.
Security Fix(es):
* openvswitch: Mishandle of group mods in lib/ofp-util.c:parse_group_prop_ntr_selection_method() allows for assertion failure (CVE-2018-17204)
* openvswitch: Error during bundle commit in ofproto/ofproto.c:ofproto_rule_insert__() allows for crash (CVE-2018-17205)
* openvswitch: Buffer over-read in lib/ofp-actions.c:decode_bundle() (CVE-2018-17206)
For more details about the security issue(s), including the impact, a CVSS score, and other related information, refer to the CVE page(s) listed in the References section.
Bug Fix(es):
* Previously, the first packet of a new connection using an OVN logical router was used to discover the MAC address of the destination. This resulted in the loss of the first packet on the new connection. This enhancement adds the capability to correctly queue the first packet of a new connection, which prevents the loss of that packet. (BZ#1600115)
