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.
The subscription-manager packages provide programs and libraries to allow users to manage subscriptions and yum repositories from the Red Hat entitlement platform. The subscription-manager-migration-data package provides certificates for migrating a system from the legacy Red Hat Network Classic to Red Hat Subscription Management. The python-rhsm packages provide a library for communicating with the representational state transfer interface of a Red Hat Unified Entitlement Platform. The Subscription Management tools use this interface to manage system entitlements, certificates, and access to content.
