It was discovered that keycloak-httpd-client-install uses a predictable log file name in /tmp. A local attacker could create a symbolic link to a sensitive location, possibly causing data corruption or denial of service.(CVE-2017-15111)
In keycloak-http-client-install prior to version 0.8, the admin password could be provided through a command-line argument. This might result in the password being leaked through shell history, or becoming visible to a local attacker at the time the program is running.(CVE-2017-15112)
