RHEL 6 : openstack-keystone (RHSA-2014:0994)

high Nessus Plugin ID 210147

Synopsis

The remote Red Hat host is missing one or more security updates for openstack-keystone.

Description

The remote Redhat Enterprise Linux 6 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2014:0994 advisory.

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.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the RHEL openstack-keystone package based on the guidance in RHSA-2014:0994.
