Summary
An issue was discovered in Open vSwitch (OvS) 2.7.x through 2.7.6, affecting parse_group_prop_ntr_selection_method in lib/ofp-util.c. When decoding a group mod, it validates the group type and command after the whole group mod has been decoded. The OF1.5 decoder, however, tries to use the type and command earlier, when it might still be invalid. This causes an assertion failure (via OVS_NOT_REACHED). ovs-vswitchd does not enable support for OpenFlow 1.5 by default.

Summary
Red Hat Security Advisory: openvswitch security, bug fix, and enhancement update
Notes
Topic
An update for openvswitch is now available for Fast Datapath for Red Hat Enterprise Linux 7.
Red Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.
Details
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, when the ovs-vswitchd service restarted, an error displayed with many open files. With this update, the number of sockets opened by ovs-vswitchd is decreased. As a result, the described problem no longer occurs. (BZ#1526306)
* Previously, when OpenvSwitch service was reloaded, the default flow was not removed and it became part of the final flow table. With this update, the default flow rule is no longer added after a service reload. As a result, the described problem no longer occurs. (BZ#1626096)
Enhancement(s):
* With this update, the pmd-rxq-assign configuration has been added to Poll Mode Drivers (PMDs) cores. This allows users to select a round-robin assignment. (BZ#1616001)
* With this update the ovs-appctl connection-status command has been introduced to the ovs-appctl utility. The command enables to monitor hypervisor (HV) south bound database (SBDB) connection status. Layered products can now check if the ovn-controller is properly connected to a central node. (BZ#1593804)
* With this update, a support for the Dynamic Host Configuration Protocol (DHCP) option 252 has been added to Open Virtual Network (OVN) Native DHCP. (BZ#1641765)

Summary
Red Hat Security Advisory: openvswitch security and bug fix update
Notes
Topic
An update for openvswitch is now available for Red Hat OpenStack Platform 13.0 (Queens).
Red Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.
Details
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)

Severity ?
Summary
An issue was discovered in Open vSwitch (OvS) 2.7.x through 2.7.6, affecting parse_group_prop_ntr_selection_method in lib/ofp-util.c. When decoding a group mod, it validates the group type and command after the whole group mod has been decoded. The OF1.5 decoder, however, tries to use the type and command earlier, when it might still be invalid. This causes an assertion failure (via OVS_NOT_REACHED). ovs-vswitchd does not enable support for OpenFlow 1.5 by default.

Details
An issue was discovered in Open vSwitch (OvS) 2.7.x through 2.7.6, affecting parse_group_prop_ntr_selection_method in lib/ofp-util.c. When decoding a group mod, it validates the group type and command after the whole group mod has been decoded. The OF1.5 decoder, however, tries to use the type and command earlier, when it might still be invalid. This causes an assertion failure (via OVS_NOT_REACHED). ovs-vswitchd does not enable support for OpenFlow 1.5 by default.

Details
An issue was discovered in Open vSwitch (OvS) 2.7.x through 2.7.6, affecting parse_group_prop_ntr_selection_method in lib/ofp-util.c. When decoding a group mod, it validates the group type and command after the whole group mod has been decoded. The OF1.5 decoder, however, tries to use the type and command earlier, when it might still be invalid. This causes an assertion failure (via OVS_NOT_REACHED). ovs-vswitchd does not enable support for OpenFlow 1.5 by default.
