Descriptions

keycloak-httpd-client-install versions before 0.8 insecurely creates temporary file allowing local attackers to overwrite other files via symbolic link.

keycloak-httpd-client-install, en versiones anteriores a la 0.8, crea archivos temporales de forma insegura, lo que permite que atacantes locales sobrescriban otros archivos mediante un enlace simbólico.

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.

The keycloak-httpd-client-install packages provide various libraries and tools that can automate and simplify the configuration of Apache httpd authentication modules when registering as a Red Hat Single Sign-On federated Identity Provider client. Multiple unsafe actions have been addressed.
