[Secure-testing-team] Bug#700947: CVE-2013-0282: Ensure EC2 users and tenant are enabled

[Thomas Goirand]

Package: keystone
Version: 2012.1.1-12
Severity: grave
Tags: security

Nathanael Burton reported a vulnerability in EC2-style authentication in
Keystone. Keystone fails to check whether a user, tenant, or domain is enabled
before authenticating a user using the EC2 api. Authenticated, but disabled
users (or authenticated users in disabled tenants or domains) could therefore
retain access rights that were thought removed. Only setups enabling EC2-style
authentication are affected. To disable EC2-style authentication to work
around the issue, remove the EC2 extension from the keystone API pipeline in
keystone.conf.

Patched version is ready, upload is comming.
