Descriptions

The Subscription Manager package (aka subscription-manager) before 1.17.7-1 for Candlepin uses weak permissions (755) for subscription-manager cache directories, which allows local users to obtain sensitive information by reading files in the directories.

El paquete Subscription Manager (también conocido como subscription-manager) en versiones anteriores a 1.17.7-1 para Candlepin utiliza permisos débiles (755) para los directorios de caché del subscription-manager, lo que permite a los usuarios locales obtener información sensible leyendo archivos en los directorios.

It was found that subscription-manager set weak permissions on files in /var/lib/rhsm/, causing an information disclosure. A local, unprivileged user could use this flaw to access sensitive data that could potentially be used in a social engineering attack.
