Detail

Problem Description:

An updated openstack-packstack package that fixes two security issues and several bugs is now available for Red Hat OpenStack Folsom.

The Red Hat Security Response Team has rated this update as having moderate 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:

OpenStack Folsom - noarch

3. Description:

PackStack is a command line utility that uses Puppet modules to support rapid deployment of OpenStack on existing servers over an SSH connection. PackStack is suitable for deploying both single node proof of concept installations and more complex multi-node installations.

A flaw was found in PackStack. During manifest creation, the manifest file was written to /tmp/ with a predictable file name. A local attacker could use this flaw to perform a symbolic link attack, overwriting an arbitrary file accessible to the user running PackStack with the contents of the manifest, which could lead to a denial of service. Additionally, the attacker could read and potentially modify the manifest being generated, allowing them to modify systems being deployed using OpenStack. (CVE-2013-0261)

It was discovered that the cinder.conf and all api-paste.ini configuration files were created with world-readable permissions. A local attacker could use this flaw to view administrative passwords, allowing them to control systems deployed and managed by OpenStack. (CVE-2013-0266)

The CVE-2013-0261 issue was discovered by Kurt Seifried of the Red Hat Security Response Team, and CVE-2013-0266 was discovered by Derek Higgins of the Red Hat OpenStack team.

This update also fixes several bugs in the openstack-packstack package.

All users of openstack-packstack are advised to upgrade to this updated package, which corrects these issues.

4. Solution:

Before applying this update, make sure all previously-released errata relevant to your system have been applied.
