Ubuntu Security Notice (C) 2012-2016 Canonical, Inc. / NASL script (C) 2012-2016 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
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.
