high Tenable Self-Hosted Container Security Plugin ID 434434

Description

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

 - 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

 leveraged for other unrelated attacks. All deployments enabling
 security_compliance.lockout_failure_attempts are affected. (CVE-2021-38155)
