Security Advisory Moderate: openstack-packstack security and bug fix update

Advisory: RHSA-2013:0671-1
Type: Security Advisory
Severity: Moderate
Issued on: 2013-03-21
Last updated on: 2013-03-21
Affected Products: Red Hat OpenStack Folsom
CVEs ( CVE-2013-1815


An updated openstack-packstack package that fixes one security issue 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. A Common Vulnerability Scoring System (CVSS) base score,
which gives a detailed severity rating, is available from the CVE link in
the References section.

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.

It was found that PackStack did not handle the answer file securely. In
some environments, such as those using a non-default umask, a local
attacker could possibly modify the answer file if PackStack was run in an
attacker controlled directory, or attempted to create the answer file in
"/tmp/", allowing the attacker to modify systems being deployed using
OpenStack. Note: After applying this update, PackStack will create the
answer file in the user's home directory by default. It will no longer
create it in the current working directory or the "/tmp/" directory by
default. (CVE-2013-1815)

The CVE-2013-1815 issue 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.


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

This update is available via the Red Hat Network. Details on how to
