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.

affected by a major bug. This bug renders building and testing
security updates of OpenStack components difficult, due to
random crashes during building or testing, particularly
keystone component.

For Debian 10 buster, this problem has been fixed in version
1.3.0-1+deb10u1.
