Descriptions

A NULL pointer dereference was found in the libvirt API responsible introduced in upstream version 3.10.0, and fixed in libvirt 6.0.0, for fetching a storage pool based on its target path. In more detail, this flaw affects storage pools created without a target path such as network-based pools like gluster and RBD. Unprivileged users with a read-only connection could abuse this flaw to crash the libvirt daemon, resulting in a potential denial of service.

Se detectó una desreferencia del puntero NULL en la API libvirt responsable que la introdujo en la versión anterior a 3.10.0, y corregida en libvirt versión 6.0.0, para extraer un grupo de almacenamiento basado en su ruta de destino. En más detalle, este fallo afecta a los grupos de almacenamiento creados sin una ruta de destino, tales como los grupos basados en red tales como Gluster y RBD. Los usuarios no privilegiados con una conexión de solo lectura podrían abusar de este fallo para bloquear el demonio de libvirt, resultando en una potencial denegación de servicio.
