Descriptions

xend in Xen 3.0.3 does not properly limit the contents of the /local/domain xenstore directory tree, and does not properly restrict a guest VM's write access within this tree, which allows guest OS users to cause a denial of service and possibly have unspecified other impact by writing to (1) console/tty, (2) console/limit, or (3) image/device-model-pid. NOTE: this issue was originally reported as an issue in libvirt 0.3.3 and xenstore, but CVE is considering the core issue to be related to Xen.

libvirt v0.3.3 se basa en ficheros localizados bajo subdirectorios de /local/domain en xenstore a pesar de la falta de protección contra modificaciones introducida por Xen en máquinas virtuales invitado, lo cual permite a usuarios del sistema operativo (SO) huésped tener un impacto desconocido, como lo demostrado mediante la escritura en (1) consola de texto (console/tty) o (2) el puerto VNC para el gráfico framebuffer.
