RHSA-2015:1685 - Security Advisory

Topic

Updated python-keystoneclient packages that fix one security issue are
now available for Red Hat Enterprise Linux OpenStack Platform 5.0.

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.

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.
