Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- 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-2020-17376)
