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.
