Description

Security Fix(es):

• An information-disclosure flaw was found in oslo.middleware. Software using the CatchError class could include sensitive values in a traceback's error message. Remote users could exploit this flaw to obtain sensitive information from OpenStack component error logs (for example, keystone tokens). (CVE-2017-2592)
