How to fix?

Upgrade Debian:11 nova to version 2014.1.1-8 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream nova package and not the nova package as distributed by Debian. See How to fix? for Debian:11 relevant fixed versions and status.

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 responses to instance metadata requests.
