Ubuntu Security Notice (C) 2013-2016 Canonical, Inc. / NASL script (C) 2013-2016 Tenable Network Security, Inc.
The remote Ubuntu host is missing a security-related patch.
Steven Hardy discovered that Keystone did not properly enforce trusts
when using the ec2tokens API. An authenticated attacker could exploit
this to retrieve a token not scoped to the trust and elevate
privileges to the trustor's roles.
Note that Tenable Network Security has extracted the preceding
description block directly from the Ubuntu security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues.
Update the affected python-keystone package.
