CVE-2013-0153 – kernel: xen: interrupt remap entries shared and old ones not cleared on AMD IOMMUs
https://notcve.org/view.php?id=CVE-2013-0153
The AMD IOMMU support in Xen 4.2.x, 4.1.x, 3.3, and other versions, when using AMD-Vi for PCI passthrough, uses the same interrupt remapping table for the host and all guests, which allows guests to cause a denial of service by injecting an interrupt into other guests. El soporte de Xen para AMD IOMMU en v4.2.x, v4.1.x, v3.3, and otras versiones, cuando usa AMD-Vi para el paso por el PCI, usa la misma tabla para el trazado de interrupciones por el host y los anfitriones, lo que permite a los invitados causar una denegación de servicio por medio de la inyección de una interrupción en los otros invitados. • http://lists.opensuse.org/opensuse-security-announce/2014-03/msg00021.html http://lists.opensuse.org/opensuse-updates/2013-04/msg00051.html http://lists.opensuse.org/opensuse-updates/2013-04/msg00052.html http://lists.opensuse.org/opensuse-updates/2013-06/msg00049.html http://osvdb.org/89867 http://rhn.redhat.com/errata/RHSA-2013-0847.html http://secunia.com/advisories/51881 http://secunia.com/advisories/55082 http://security.gentoo.org/glsa/glsa-201309-24.xml http://www.deb •
