+             Xen Security Advisory CVE-2011-2901 / XSA-4
+                        revision no.2
+        Xen <= 3.3 DoS due to incorrect virtual address validation
+
+ISSUE DESCRIPTION
+=================
+
+The x86_64 __addr_ok() macro intends to ensure that the checked
+address is either in the positive half of the 48-bit virtual address
+space, or above the Xen-reserved area. However, the current shift
+count is off-by-one, allowing full access to the "negative half" too,
+via certain hypercalls which ignore virtual-address bits [63:48].
+Vulnerable hypercalls exist only in very old versions of the
+hypervisor.
+
+VULNERABLE SYSTEMS
+==================
+
+All systems running a Xen 3.3 or earlier hypervisor with 64-bit PV
+guests with untrusted administrators are vulnerable.
+
+IMPACT
+======
+
+A malicious guest administrator on a vulnerable system is able to
+crash the host.
+
+There are no known further exploits but these have not been ruled out.
+
+RESOLUTION
+==========
+
+The attached patch resolves the issue.
+
+Alternatively, users may choose to upgrade to a more recent hypervisor
+
+PATCHES
+=======
+
+The following patch resolves this issue.
+
+Filename: fix-__addr_ok-limit.patch
+SHA1: f18bde8d276110451c608a16f577865aa1226b4f
+SHA256: 2da5aac72e1ac4849c34d38374ae456795905fd9512eef94b48fc31383c21636
+
+This patch should apply cleanly, and fix the problem, for all affected
+versions of Xen.
+
+It is harmless when applied to later hypervisors and will be included
+in the Xen unstable branch in due course.
+
+VERSION HISTORY
+===============
+
+Analysis following version 1 of this advisory (sent out to the
+predisclosure list during the embargo period) indicates that the
+actual DoS vulnerability only exists in very old hypervisors, Xen 3.3
+and earlier, contrary to previous reports.
+
+This advisory is no longer embargoed.

+Subject: XSA-4: xen: correct limit checking in x86_64 version of __addr_ok
+
+The x86_64 __addr_ok() macro intends to ensure that the checked
+address is either in the positive half of the 48-bit virtual address
+space, or above the Xen-reserved area. However, the current shift
+count is off-by-one, allowing full access to the "negative half"
+too. Guests may exploit this to gain access to off-limits ranges.
+
+This issue has been assigned CVE-2011-2901.

+             Xen Security Advisory CVE-2011-2901 / XSA-4
+                        revision no.2
+        Xen <= 3.3 DoS due to incorrect virtual address validation
+
+ISSUE DESCRIPTION
+=================
+
+The x86_64 __addr_ok() macro intends to ensure that the checked
+address is either in the positive half of the 48-bit virtual address
+space, or above the Xen-reserved area. However, the current shift
+count is off-by-one, allowing full access to the "negative half" too,
+via certain hypercalls which ignore virtual-address bits [63:48].
+Vulnerable hypercalls exist only in very old versions of the
+hypervisor.
+
+VULNERABLE SYSTEMS
+==================
+
+All systems running a Xen 3.3 or earlier hypervisor with 64-bit PV
+guests with untrusted administrators are vulnerable.
+
+IMPACT
+======
+
+A malicious guest administrator on a vulnerable system is able to
+crash the host.
+
+There are no known further exploits but these have not been ruled out.
+
+RESOLUTION
+==========
+
+The attached patch resolves the issue.
+
+Alternatively, users may choose to upgrade to a more recent hypervisor
+
+PATCHES
+=======
+
+The following patch resolves this issue.
+
+Filename: fix-__addr_ok-limit.patch
+SHA1: f18bde8d276110451c608a16f577865aa1226b4f
+SHA256: 2da5aac72e1ac4849c34d38374ae456795905fd9512eef94b48fc31383c21636
+
+This patch should apply cleanly, and fix the problem, for all affected
+versions of Xen.
+
+It is harmless when applied to later hypervisors and will be included
+in the Xen unstable branch in due course.
+
+VERSION HISTORY
+===============
+
+Analysis following version 1 of this advisory (sent out to the
+predisclosure list during the embargo period) indicates that the
+actual DoS vulnerability only exists in very old hypervisors, Xen 3.3
+and earlier, contrary to previous reports.
+
+This advisory is no longer embargoed.

+Subject: XSA-4: xen: correct limit checking in x86_64 version of __addr_ok
+
+The x86_64 __addr_ok() macro intends to ensure that the checked
+address is either in the positive half of the 48-bit virtual address
+space, or above the Xen-reserved area. However, the current shift
+count is off-by-one, allowing full access to the "negative half"
+too. Guests may exploit this to gain access to off-limits ranges.
+
+This issue has been assigned CVE-2011-2901.

+# HG changeset patch
+# User Tim Deegan <Tim.Deegan@citrix.com>
+# Date 1313145221 -3600
+# Node ID 84e3706df07a1963e23cd3875d8603917657d462
+# Parent  cb22fa57ff252893b6adb1481e09b1287eacd990
+Passthrough: disable bus-mastering on any card that causes an IOMMU fault.
+
+This stops the card from raising back-to-back faults and live-locking
+the CPU that handles them.

+the CPU that handles them.
