Open vSwitch provides standard network bridging functions and support for
the OpenFlow protocol for remote per-flow control of traffic.

Security Fix(es):

  • openvswitch: limitation in the OVS packet parsing in userspace leads to DoS (CVE-2020-35498)

  • lldp/openvswitch: 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(s) listed in the References section.
