Summary: An update for openvswitch is now available for Red Hat OpenStack Platform 8.0 (Liberty). 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. 2. Relevant releases/architectures: Red Hat OpenStack Platform 8.0 (Liberty) - noarch, x86_64 3. Description: Open vSwitch provides standard network bridging functions and support for the OpenFlow protocol for remote per-flow control of traffic. Security Fix(es): * An unsigned integer wrap around that led to a buffer over-read was found when parsing OFPT_QUEUE_GET_CONFIG_REPLY messages in Open vSwitch (OvS). An attacker could use this issue to cause a remote denial of service attack. (CVE-2017-9214) * While parsing an OpenFlow role status message Open vSwitch (OvS), a call to the abort() function for undefined role status reasons in the function 'ofp_print_role_status_message' in 'lib/ofp-print.c' could be misused for a remote denial of service attack by a malicious switch. (CVE-2017-9263) * A buffer over-read issue was found in Open vSwitch (OvS) which emerged while parsing the GroupMod OpenFlow messages sent from the controller. The issue could enable an attacker to cause a denial of service type of attack. (CVE-2017-9265) 4.
