CVE-2019-9735 (opens in a new tab)How to fix?
Upgrade RHEL:7 openstack-neutron-ml2 to version 1:9.4.1-40.el7ost or higher.
This issue was patched in RHSA-2019:0916.
NVD Description
Note: Versions mentioned in the description apply only to the upstream openstack-neutron-ml2 package and not the openstack-neutron-ml2 package as distributed by RHEL.
See How to fix? for RHEL:7 relevant fixed versions and status.
An issue was discovered in the iptables firewall module in OpenStack Neutron before 10.0.8, 11.x before 11.0.7, 12.x before 12.0.6, and 13.x before 13.0.3. By setting a destination port in a security group rule along with a protocol that doesn't support that option (for example, VRRP), an authenticated user may block further application of security group rules for instances from any project/tenant on the compute hosts to which it's applied. (Only deployments using the iptables security group driver are affected.)
