How to fix?

There is no fixed version for Debian:9 keystone.

NVD Description

Note: Versions mentioned in the description apply only to the upstream keystone package and not the keystone package as distributed by Debian. See How to fix? for Debian:9 relevant fixed versions and status.

OpenStack Keystone 10.x through 16.x before 16.0.2, 17.x before 17.0.1, 18.x before 18.0.1, and 19.x before 19.0.1 allows information disclosure during account locking (related to PCI DSS features). By guessing the name of an account and failing to authenticate multiple times, any unauthenticated actor could both confirm the account exists and obtain that account's corresponding UUID, which might be leveraged for other unrelated attacks. All deployments enabling security_compliance.lockout_failure_attempts are affected.
