OpenStack Compute (Nova) Exposure of Sensitive Information to an Unauthorized Actor vulnerability

api/metadata/handler.py in OpenStack Compute Nova before 2013.2.4, 2014.x before 2014.1.2, and Juno before Juno-2, when proxying metadata requests through Neutron, makes it easier for remote attackers to guess instance ID signatures via a brute-force attack that relies on timing differences in...

GHSA-8Q95-JJ7P-X93X Openstack Neutron vulnerable to eavesdropping on private traffic

Live-migrated instances are briefly able to inspect traffic for other instances on the same hypervisor. This brief window could be extended indefinitely if the instance's port is set administratively down prior to live-migration and kept down after the migration is complete. This is possible due ...

OpenStack Neutron overlapping security group rules prevents compute node network configuration

An issue was discovered in OpenStack Neutron 11.x before 11.0.7, 12.x before 12.0.6, and 13.x before 13.0.3. By creating two security groups with separate/overlapping port ranges, an authenticated user may prevent Neutron from being able to configure networks on any compute nodes where those...

OpenStack Neutron's unsupported dport option prevents applying security groups

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...

GHSA-X634-34M9-96MP OpensStack Neutron Denial of Service Vulnerability

When using the Linux bridge ml2 driver, non-privileged tenants are able to create and attach ports without specifying an IP address, bypassing IP address validation. A potential denial of service could occur if an IP address, conflicting with existing guests or routers, is then assigned from...
