    Synopsis:          Important: openstack-keystone security update
    Advisory ID:       RHSA-2014:0994-01
    Product:           Red Hat Enterprise Linux OpenStack Platform
    Advisory URL:      https://rhn.redhat.com/errata/RHSA-2014-0994.html
    Issue date:        2014-07-31
    CVE Names:         CVE-2014-3476 CVE-2014-3520 
    =====================================================================
    
    1. Summary:
    
    Updated openstack-keystone packages that fix two security issues are now
    available for Red Hat Enterprise Linux OpenStack Platform 3.0 and 4.0.
    
    The Red Hat Security Response Team has rated this update as having
    Important security impact. Common Vulnerability Scoring System (CVSS) base
    scores, which give detailed severity ratings, are available for each
    vulnerability from the CVE links in the References section.
    
    2. Relevant releases/architectures:
    
    Red Hat Enterprise Linux OpenStack Platform 3.0 - noarch
    Red Hat Enterprise Linux OpenStack Platform 4.0 - noarch
    
    3. Description:
    
    The OpenStack Identity service (keystone) authenticates and authorizes
    OpenStack users by keeping track of users and their permitted activities.
    The Identity service supports multiple forms of authentication, including
    user name and password credentials, token-based systems, and AWS-style
    logins.
    
    A flaw was found in keystone's chained delegation. A trustee able to create
    a delegation from a trust or an OAuth token could misuse identity
    impersonation to bypass the enforced scope, possibly allowing them to
    obtain elevated privileges to the trustor's projects and roles.
    (CVE-2014-3476)
    
    A flaw was found in the way keystone handled trusts. A trustee could use an
    out-of-scope project ID to gain unauthorized access to a project if the
    trustor had the required roles for that requested project. (CVE-2014-3520)
    
    Red Hat would like to thank the OpenStack project for reporting
    CVE-2014-3520; upstream acknowledges Jamie Lennox of Red Hat as the
    original reporter. The CVE-2014-3476 issue was discovered by Steven Hardy
    of Red Hat.
    
    All openstack-keystone users are advised to upgrade to these updated
    packages, which correct these issues.
