Description Pedro Sampaio 2017-11-09 13:02:36 EST 
A flaw was discovered in keycloak-httpd-client-install version 0.6-2. The --log-file option in keycloak_cli.py insecurely passes the script name for the log file creation.
Comment 1 John Dennis 2017-11-09 13:52:15 EST 
Could you please explain the security issue, I do not follow from the terse "insecurely passes the script name for the log file creation" phrase.

Red Hat Product Security has rated this issue as having security impact of Low. This issue may be fixed in a future version of Red Hat Enterprise Linux.

OpenStack users please note, this issue is present in:
* Red Hat OpenStack Platform 9.0 (Mitaka)
* Red Hat OpenStack Platform 10.0 (Newton)
