"The remote Debian 10 host has packages installed that are affected by multiple vulnerabilities as referenced in the
dla-3714 advisory.

  - A flaw was found in openstack-keystone. Only the first 72 characters of an application secret are verified
    allowing attackers bypass some password complexity which administrators may be counting on. The highest
    threat from this vulnerability is to data confidentiality and integrity. (CVE-2021-3563)

  - 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. (CVE-2021-38155)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version
number.");
