Notes

Topic
An update for openvswitch2.11 is now available for Red Hat OpenStack Platform 13 (Queens). Red Hat Product Security has rated this update as having a security impact of Important. 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): * limitation in the OVS packet parsing in userspace leads to DoS (CVE-2020-35498) * denial of service via externally triggered memory leak (CVE-2020-27827) For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page listed in the References section.
