CVE-2015-1852
Description
It was discovered that some items in the S3Token paste configuration as used by python-keystonemiddleware (formerly python-keystoneclient) were incorrectly evaluated as strings, an issue similar to CVE-2014-7144. If the "insecure" option were 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.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
