RedHat: RHSA-2019-0081:01 Moderate: openvswitch security and bug fix update
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)
