Ubuntu Security Notice (C) 2012-2013 Canonical, Inc. / NASL script (C) 2012-2013 Tenable Network Security, Inc.
The remote Ubuntu host is missing a security-related patch.
Vijaya Erukala discovered that Keystone did not properly invalidate
EC2-style credentials such that if credentials were removed from a
tenant, an authenticated and authorized user using those credentials
may still be allowed access beyond the account owner's expectations.
It was discovered that Keystone did not properly implement token
expiration. A remote attacker could use this to continue to access an
account that is disabled or has a changed password. This issue was
previously fixed as CVE-2012-3426 but was reintroduced in Ubuntu
Update the affected python-keystone package.
