Package : keystone Version : 2:14.2.0-0+deb10u2 CVE ID : CVE-2021-3563 CVE-2021-38155 Debian Bug : 992070 989998

Brief introduction

CVE-2021-3563

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-2021-38155

Keystone allowed 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.

For Debian 10 buster, these problems have been fixed in version 2:14.2.0-0+deb10u2.

We recommend that you upgrade your keystone packages.
