Descriptions

The backend for XenSource Xen Para Virtualized Frame Buffer (PVFB) in Xen ioemu does not properly restrict the frame buffer size, which allows attackers to cause a denial of service (crash) by mapping an arbitrary amount of guest memory.

El backend para XenSource Xen Para Virtualized Frame Buffer (PVFB) en Xen ioemu, no restringe apropiadamente el tamaño del búfer de trama, lo que permite a los atacantes causar una denegación de servicio (bloqueo) mediante la asignación de una cantidad arbitraria de memoria de invitado.
