The s3_token middleware in OpenStack keystonemiddleware before 1.6.0 and python-keystoneclient before 1.4.0 disables certification verification when the "insecure" option is set in a paste configuration (paste.ini) file regardless of the value, which allows remote attackers to conduct man-in-the-middle attacks via a crafted certificate, a different vulnerability than CVE-2014-7144.

The remote Redhat Enterprise Linux 6 / 7 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2015:1685 advisory.

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

    It was discovered that some items in the S3Token configuration as used by     python-keystoneclient were incorrectly evaluated as strings, an issue     similar to CVE-2014-7144. If the insecure option was set to false, the     option would be evaluated as true, resulting in TLS connections being     vulnerable to man-in-the-middle attacks. Note: The insecure option     defaults to false, so setups that do not specifically define     insecure=false are not affected. (CVE-2015-1852)

    Red Hat would like to thank the OpenStack project for reporting this issue.
    Upstream acknowledges Brant Knudson from IBM as the original reporter.

    All python-keystoneclient users are advised to upgrade to these updated     packages, which contain a backported patch to correct this issue.

There are packages installed that are affected by a vulnerability referenced in the following CVE:

  - The s3_token middleware in OpenStack keystonemiddleware before 1.6.0 and python-keystoneclient before
    1.4.0 disables certification verification when the "insecure" option is set in a paste configuration
    (paste.ini) file regardless of the value, which allows remote attackers to conduct man-in-the-middle
