3. 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.

4. Solution:

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