GHSA-hvxr-2fvv-c3wq OpenStack Neutron Race Condition vulnerability

• PyPI neutron: < 7.2.0-12.1 → fixed in 7.2.0-12.1 • PyPI neutron: >= 8.0.0, < 8.3.0-11.1 → fixed in 8.3.0-11.1 • PyPI neutron: >= 9.0.0, < 9.3.1-2.1 → fixed in 9.3.1-2.1 • PyPI neutron: >= 10.0.0, < 10.0.2-1.1 → fixed in 10.0.2-1.1

A race-condition flaw was discovered in openstack-neutron before 7.2.0-12.1, 8.x before 8.3.0-11.1, 9.x before 9.3.1-2.1, and 10.x before 10.0.2-1.1, where, following a minor overcloud update, neutron security groups were disabled. Specifically, the following were reset to 0: net.bridge.bridge-nf-call-ip6tables and net.bridge.bridge-nf-call-iptables. The race was only triggered by an update, at which point an attacker could access exposed tenant VMs and network resources.
