The handle_mmio function in arch/x86/hvm/io.c in the MMIO operations emulator for Xen 3.3 and 4.x, when running an HVM guest, does not properly reset certain state information between emulation cycles, which allows local guest OS users to cause a denial of service (guest OS crash) via unspecified operations on MMIO regions. La función handle_mmio en arch/x86/hvm/io.c en el emulador de operaciones MMIO para Xen v3.3 y v4.x, cuando se ejecuta un HVM huesped, no reinicia correctamente la información de estado entre determinados ciclos de emulación, lo que permite a los usuarios del sistema operativo huésped provocar una denegación de servicio (caída de OS huesped) a través de operaciones no especificadas en las regiones MMIO. • http://lists.opensuse.org/opensuse-security-announce/2012-08/msg00024.html http://lists.opensuse.org/opensuse-security-announce/2012-08/msg00025.html http://lists.opensuse.org/opensuse-security-announce/2012-09/msg00017.html http://lists.opensuse.org/opensuse-security-announce/2012-09/msg00018.html http://lists.xen.org/archives/html/xen-devel/2012-07/msg01649.html http://secunia.com/advisories/55082 http://security.gentoo.org/glsa/glsa-201309-24.xml http://www.debian.org/security/2012/ds • CWE-264: Permissions, Privileges, and Access Controls •
