Descriptions

libgio, when used in setuid or other privileged programs in spice-gtk and possibly other products, allows local users to gain privileges and execute arbitrary code via the DBUS_SYSTEM_BUS_ADDRESS environment variable. NOTE: it could be argued that this is a vulnerability in the applications that do not cleanse environment variables, not in libgio itself.

libgio, cuando se utiliza setuid u otros programas con privilegios en spice-gtk y posiblemente otros productos, permite a usuarios locales obtener privilegios y ejecutar código de su elección a través de la variable de entorno DBUS_SYSTEM_BUS_ADDRESS. NOTA: Se podría argumentar que se trata de una vulnerabilidad en las aplicaciones que limpian las variables de entorno, no solo en libgio en sí.
