Descriptions

The xenmem_add_to_physmap_one function in arch/arm/mm.c in Xen 4.5.x, 4.4.x, and earlier does not limit the number of printk console messages when reporting a failure to retrieve a reference on a foreign page, which allows remote domains to cause a denial of service by leveraging permissions to map the memory of a foreign guest.

Vulnerabilidad en la función xenmem_add_to_physmap_one en arch/arm/mm.c en Xen 4.5.x, 4.4.x y en versiones anteriores no limita el número de mensajes de la consola de printk al informar de un fallo para recuperar la referencia a una página externa, lo que permite a dominios remotos causar una denegación de servicio mediante el aprovechamiento de permisos para asignar la memoria a un invitado ajeno.

Multiple security issues have been found in the Xen virtualisation solution, which may result in denial of service or information disclosure.
