| CVE-2020-17376 | 1 Openstack | 1 Nova | 2020-09-14 | 6.5 MEDIUM | 8.3 HIGH |
| An issue was discovered in Guest.migrate in virt/libvirt/guest.py in OpenStack Nova before 19.3.1, 20.x before 20.3.1, and 21.0.0. By performing a soft reboot of an instance that has previously undergone live migration, a user may gain access to destination host devices that share the same paths as host devices previously referenced by the virtual machine on the source host. This can include block devices that map to different Cinder volumes at the destination than at the source. Only deployments allowing host-based connections (for instance, root and ephemeral devices) are affected. | |||||
| CVE-2011-3147 | 1 Openstack | 1 Nova | 2020-09-03 | 5.0 MEDIUM | 8.6 HIGH |
| Versions of nova before 2012.1 could expose hypervisor host files to a guest operating system when processing a maliciously constructed qcow filesystem. | |||||
| CVE-2017-17051 | 1 Openstack | 1 Nova | 2019-10-03 | 4.0 MEDIUM | 8.6 HIGH |
| An issue was discovered in the default FilterScheduler in OpenStack Nova 16.0.3. By repeatedly rebuilding an instance with new images, an authenticated user may consume untracked resources on a hypervisor host leading to a denial of service, aka doubled resource allocations. This regression was introduced with the fix for OSSA-2017-005 (CVE-2017-16239); however, only Nova stable/pike or later deployments with that fix applied and relying on the default FilterScheduler are affected. | |||||
| CVE-2017-18191 | 2 Openstack, Redhat | 2 Nova, Openstack | 2019-10-03 | 7.8 HIGH | 7.5 HIGH |
| An issue was discovered in OpenStack Nova 15.x through 15.1.0 and 16.x through 16.1.1. By detaching and reattaching an encrypted volume, an attacker may access the underlying raw volume and corrupt the LUKS header, resulting in a denial of service attack on the compute host. (The same code error also results in data loss, but that is not a vulnerability because the user loses their own data.) All Nova setups supporting encrypted volumes are affected. | |||||
| CVE-2015-5162 | 1 Openstack | 3 Cinder, Glance, Nova | 2018-01-05 | 7.8 HIGH | 7.5 HIGH |
| The image parser in OpenStack Cinder 7.0.2 and 8.0.0 through 8.1.1; Glance before 11.0.1 and 12.0.0; and Nova before 12.0.4 and 13.0.0 does not properly limit qemu-img calls, which might allow attackers to cause a denial of service (memory and disk consumption) via a crafted disk image. | |||||
