CVE-2013-2144

Red Hat Enterprise Virtualization Manager (RHEVM) anterior a 3.2, no maneja adecuadamente los permisos para el dominio de almacenamiento objetivo, lo que permite a atacantes provocar una denegación de servicio (consumo de espacio de disco) mediante el clonado de una máquina virtual desde un SnapShot.

Red Hat Enterprise Virtualization Manager is a visual tool for centrally managing collections of virtual servers running Red Hat Enterprise Linux and Microsoft Windows. This package also includes the Red Hat Enterprise Virtualization Manager API, a set of scriptable commands that give administrators the ability to perform queries and operations on Red Hat Enterprise Virtualization Manager. It was found that permission checks were not performed on the target storage domain when cloning a virtual machine from a snapshot. An attacker could use this flaw to perform a denial of service attack, exhausting free disk space on the target storage domain.
