CVE-2013-0153

CVE-2013-0153 affects the AMD IOMMU (AMD-Vi) interrupt remapping: Xen hypervisor in versions including 4.2.x, 4.1.x and 3.3 (and others) reuses a single interrupt remapping table for host and guests, allowing a guest to inject interrupts into other guests and cause a denial of service. Connected ...

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...

interrupt remap entries shared and old ones not cleared on AMD IOMMUs

ISSUE DESCRIPTION To avoid an erratum in early hardware, the Xen AMD IOMMU code by default chooses to use a single interrupt remapping table for the whole system. This sharing implies that any guest with a passed through PCI device that is bus mastering capable can inject interrupts into other...

SuSE 11.1 Security Update : Xen (SAT Patch Number 6399)

Three security issues were found in XEN. Two security issues are fixed by this update : - Due to incorrect fault handling in the XEN hypervisor it was possible for a XEN guest domain administrator to execute code in the XEN host environment. CVE-2012-0217 - Also a guest user could crash the guest...

nested virtualization on 32-bit exposes host crash

ISSUE DESCRIPTION When performing nested virtualisation Xen would incorrectly map guest pages for extended periods using an interface which is only intended for transient mappings. In some configurations there are a limited number of slots available for these transient mappings and exhausting the...

CVE-2012-2934

CVE-2012-2934 affects Xen 4.0/4.1 when a 64‑bit PV guest runs on older AMD CPUs; Xen fails to detect AMD Erratum #121, allowing a local unprivileged guest to cause a host hang (crash) via non‑canonical address handling. Debians/Red Hat advisories note mitigations: upgrade Xen to fixed releases (e...

Scientific Linux Security Update : kernel on SL4.x i386/x86_64

A flaw was found in the handling of process death signals. This allowed a local user to send arbitrary signals to the suid-process executed by that user. A successful exploitation of this flaw depends on the structure of the suid-program and its signal handling. CVE-2007-3848, Important - A flaw...
