openstack-nova: Compute service fails to restart if the vnic_type of a bound port changed from direct to macvtap

An issue was discovered in OpenStack Nova before 23.2.2, 24.x before 24.1.2, and 25.x before 25.0.2. By creating a neutron port with the direct vnictype, creating an instance bound to that port, and then changing the vnictype of the bound port to macvtap, an authenticated user may cause the compu...

Ubuntu 16.04 ESM / 18.04 LTS / 20.04 LTS : Nova vulnerabilities (USN-5866-1)

The remote Ubuntu 16.04 ESM / 18.04 LTS / 20.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-5866-1 advisory. It was discovered that Nova did not properly manage data logged into the log file. An attacker with read access to the service's...

Denial Of Service (DoS)

Nova is vulnerable to denial of service DoS due to changing neutron ports. An attacker creates a neutron port with the direct vnictype, instantiates an instance bound to the port, then changes the bound port to macvtap, resulting in compute services failure to restart, leading to a denial of...
