"The remote Red Hat host is missing a security update for python-keystoneclient.");

"The remote Redhat Enterprise Linux 7 host has packages installed that are affected by a vulnerability as referenced in
the RHSA-2014:1784 advisory.

    Python-keystoneclient is a client library and a command line utility for
    interacting with the OpenStack Identity API.

    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.

    This update also fixes the following bugs:

    * Previously, when running Python-keystoneclient in the DEBUG log level,
    sensitive data may have been logged in plain text. Refer to the OSSN-0024
    document, linked to in the References, for further information.
    (BZ#1106328)

    * Previously, when attempting to enable the use of the s3_token middleware,
    for use with the Amazon Simple Storage Service (Amazon S3) APIs, a No
    module named webob error was returned. (BZ#1133431)

    All python-keystoneclient 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 this issue but has instead relied only on the application's self-reported version
number.");
