Description

OpenStack Networking (neutron) is a virtual network service for OpenStack.

dynamically request and configure virtual networks. These networks connect
'interfaces' from other OpenStack services (e.g. virtual NICs from Compute
VMs). The OpenStack Networking API supports extensions to provide advanced
network capabilities (e.g. QoS, ACLs, network monitoring, etc.)

Security Fix(es):

• unrestricted creation of security groups (CVE-2022-3277)
