RHSA-2015:0020 - Security Advisory

Topic

Updated python-keystoneclient packages that fix one security issue are now
available for Red Hat Enterprise Linux OpenStack Platform 4.0.

Red Hat Product Security 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.

Description

Python-keystoneclient is a client library and a command line utility for
interacting with the OpenStack Identity API. The OpenStack Identity
auth_token middleware component handles the authentication of tokens
with keystone.

It was found that python-keystoneclient treated all settings in paste.ini
files as string types. If the "insecure" option were set to any value in a
paste.ini configuration file, it would be evaluated as true, resulting in
TLS connections being vulnerable to man-in-the-middle attacks.
(CVE-2014-7144)

Note that when the "insecure" option was not set in paste.ini, it evaluated
to false, and verification was performed.

All python-keystoneclient users are advised to upgrade to these updated
packages, which correct this issue. After installing this update, all
OpenStack services using auth_token must be restarted for this update to
take effect.

Solution

Before applying this update, make sure all previously released errata
