Descriptions

Red Hat Enterprise Virtualization (RHEV) Manager before 3.5.1 ignores the permission to deny snapshot creation during live storage migration between domains, which allows remote authenticated users to cause a denial of service (prevent host start) by creating a long snapshot chain.

Red Hat Enterprise Virtualization (RHEV) Manager anterior a 3.5.1 ignora el permiso para denegar la creación de instantáneas durante la migración del almacenaje en vivo entre dominios, lo que permite a usuarios remotos autenticados causar una denegación de servicio (impedir el inicio del anfitrión) mediante la creación de una cadena larga de instantáneas.

It was discovered that the permissions to allow or deny snapshot creation were ignored during live storage migration of a VM's disk between storage domains. An attacker able to live migrate a disk between storage domains could use this flaw to cause a denial of service.
