==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 20.10

- Ubuntu 18.04 LTS
- Ubuntu 16.04 LTS

Summary:

Several security issues were fixed in Open vSwitch.

Software Description:
- openvswitch: Ethernet virtual switch

Details:

Jonas Rudloff discovered that Open vSwitch incorrectly handled certain
malformed LLDP packets. A remote attacker could use this issue to cause
Open vSwitch to crash, resulting in a denial of service, or possibly
execute arbitrary code.

Ubuntu 16.04 LTS:
