A vulnerability was found in the EC2 credentials API of Keystone, the OpenStack identity service: Any user authenticated within a limited scope (trust/oauth/application credential) could create an EC2 credential with an escalated permission, such as obtaining "admin" while the user is on a limited "viewer" role.

For the stable distribution (buster), this problem has been fixed in version 2:14.2.0-0+deb10u1.

We recommend that you upgrade your keystone packages.
