Summary

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.
