Package        : keystone
CVE ID         : not yet available
Debian Bug     : 959900

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.

For the detailed security status of keystone please refer to
its security tracker page at:
