ID CVE-2016-1571
Summary The paging_invlpg function in include/asm-x86/paging.h in Xen 3.3.x through 4.6.x, when using shadow mode paging or nested virtualization is enabled, allows local HVM guest users to cause a denial of service (host crash) via a non-canonical guest address in an INVVPID instruction, which triggers a hypervisor bug check.

    description The Xen Project reports : While INVLPG does not cause a General Protection Fault when used on a non-canonical address, INVVPID in its 'individual address' variant, which is used to back the intercepted INVLPG in certain cases, fails in such cases. Failure of INVVPID results in a hypervisor bug check. A malicious guest can crash the host, leading to a Denial of Service.

    description The remote OracleVM system is missing necessary patches to address critical security updates : - VT-d: fix TLB flushing in dma_pte_clear_one From: Jan Beulich The TLB flush code was wrong since xen-4.1.3-25.el5.127.20 (commit: vtd-Refactor-iotlb-flush-code.patch), both ovm-3.2.9 and ovm-3.2.10 were affected. The third parameter of __intel_iommu_iotlb_flush is to indicate whether the to be flushed entry was a present one. A few lines before, we bailed if !dma_pte_present(*pte), so there's no need to check the flag here again - we can simply always pass TRUE here. This is CVE-2013-6375 / XSA-78. Suggested-by: Cheng Yueqiang (cherry picked from commit 85c72f9fe764ed96f5c149efcdd69ab7c18bfe3d) (CVE-2013-6375) - x86/VMX: prevent INVVPID failure due to non-canonical guest address While INVLPG (and on SVM INVLPGA) don't fault on non-canonical addresses, INVVPID fails (in the 'individual address' case) when passed such an address. Since such intercepted INVLPG are effectively no-ops anyway, don't fix this in vmx_invlpg_intercept, but instead have paging_invlpg never return true in such a case. This is XSA-168. (CVE-2016-1571) - x86/mm: PV superpage handling lacks sanity checks MMUEXT_[,UN]MARK_SUPER fail to check the input MFN for validity before dereferencing pointers into the superpage frame table. get_superpage has a similar issue. This is XSA-167. (CVE-2016-1570) - xend/image: Don't throw VMException when using backend domains for disks. If we are using backend domains the disk image may not be accessible within the host (domain0). As such it is OK to continue on. The 'addStoreEntries' in DevController.py already does the check to make sure that when the 'backend' configuration is used - that said domain exists. As such the only change we need to do is to exclude the disk image location if the domain is not dom0. - memory: fix XENMEM_exchange error handling assign_pages can fail due to the domain getting killed in parallel, which should not result in a hypervisor crash. Also delete a redundant put_gfn - all relevant paths leading to the 'fail' label already do this (and there are also paths where it was plain wrong). All of the put_gfn-s got introduced by 51032ca058 ('Modify naming of queries into the p2m'), including the otherwise unneeded initializer for k (with even a kind of misleading comment - the compiler warning could actually have served as a hint that the use is wrong). This is XSA-159. Based on xen.org's xsa159.patch Conflicts: OVM 3.2 does not have the change (51032ca058) that is backed out in xen/common/memory.c or the put_gfn in xen/common/memory.c (CVE-2015-8339, CVE-2015-8340)

This is XSA-167. (CVE-2016-1570) - x86/HVM: avoid reading ioreq state more than once Otherwise, especially when the compiler chooses to translate the switch to a jump table, unpredictable behavior (and in the jump table case arbitrary code execution) can result. This is XSA-166. - x86: don't leak ST(n)/XMMn values to domains first using them FNINIT doesn't alter these registers, and hence using it is insufficient to initialize a guest's initial state. This is XSA-165. (CVE-2015-8555) - MSI-X: avoid array overrun upon MSI-X table writes pt_msix_init allocates msix->msix_entry[] to just cover msix->total_entries entries. While pci_msix_readl resorts to reading physical memory for out of bounds reads, pci_msix_writel so far simply accessed/corrupted unrelated memory. pt_iomem_map's call to cpu_register_physical_memory registers a page granular region, which is necessary as the Pending Bit Array may share space with the MSI-X table (but nothing else is allowed to). This also explains why pci_msix_readl actually honors out of bounds reads, but pci_msi_writel doesn't need to. This is XSA-164. (CVE-2015-8554) - From 43a10fecd6f4a9d8adf9f5d85e3d5e7187e2d54a Mon Sep 17 00:00:00 2001 From: Ian Jackson Date: Wed, 18 Nov 2015 15:34:54 +0000 Subject: [PATCH] libxl: Fix bootloader-related virtual memory leak on pv build failure The bootloader may call libxl__file_reference_map, which mmap's the pv_kernel and pv_ramdisk into process memory. This was only unmapped, however, on the success path of libxl__build_pv. If there were a failure anywhere between libxl_bootloader.c:parse_bootloader_result and the end of libxl__build_pv, the calls to libxl__file_reference_unmap would be skipped, leaking the mapped virtual memory. Ideally this would be fixed by adding the unmap calls to the destruction path for libxl__domain_build_state. Unfortunately the lifetime of the libxl__domain_build_state is opaque, and it doesn't have a proper destruction path. But, the only thing in it that isn't from the gc are these bootloader references, and they are only ever set for one libxl__domain_build_state, the one which is libxl__domain_create_state.build_state. So we can clean up in the exit path from libxl__domain_create_*, which always comes through domcreate_complete. Remove the now-redundant unmaps in libxl__build_pv's success path. This is XSA-160. Based on xen.org's xsa160.patch Conflicts: adjust patch context to match OVM 3.3 code base (CVE-2015-8341) - memory: fix XENMEM_exchange error handling assign_pages can fail due to the domain getting killed in parallel, which should not result in a hypervisor crash. Also delete a redundant put_gfn - all relevant paths leading to the 'fail' label already do this (and there are also paths where it was plain wrong).

This is XSA-159. 22326022] (CVE-2015-8339, CVE-2015-8340) - x86/HVM: always intercept #AC and #DB Both being benign exceptions, and both being possible to get triggered by exception delivery, this is required to prevent a guest from locking up a CPU (resulting from no other VM exits occurring once getting into such a loop). The specific scenarios: 1) #AC may be raised during exception delivery if the handler is set to be a ring-3 one by a 32-bit guest, and the stack is misaligned. 2) #DB may be raised during exception delivery when a breakpoint got placed on a data structure involved in delivering the exception. This can result in an endless loop when a 64-bit guest uses a non-zero IST for the vector 1 IDT entry, but even without use of IST the time it takes until a contributory fault would get raised (results depending on the handler) may be quite long. This is XSA-156. (CVE-2015-5307, CVE-2015-8104)

    description This security update fixes a number of security issues in Xen in wheezy. For Debian 7 'Wheezy', these problems have been fixed in version 4.1.6.1-1+deb7u1. We recommend that you upgrade your libidn packages. CVE-2015-2752 The XEN_DOMCTL_memory_mapping hypercall in Xen 3.2.x through 4.5.x, when using a PCI passthrough device, is not preemptable, which allows local x86 HVM domain users to cause a denial of service (host CPU consumption) via a crafted request to the device model (qemu-dm). CVE-2015-2756 QEMU, as used in Xen 3.3.x through 4.5.x, does not properly restrict access to PCI command registers, which might allow local HVM guest users to cause a denial of service (non-maskable interrupt and host crash) by disabling the (1) memory or (2) I/O decoding for a PCI Express device and then accessing the device, which triggers an Unsupported Request (UR) response. CVE-2015-5165 The C+ mode offload emulation in the RTL8139 network card device model in QEMU, as used in Xen 4.5.x and earlier, allows remote attackers to read process heap memory via unspecified vectors. CVE-2015-5307 The KVM subsystem in the Linux kernel through 4.2.6, and Xen 4.3.x through 4.6.x, allows guest OS users to cause a denial of service (host OS panic or hang) by triggering many #AC (aka Alignment Check) exceptions, related to svm.c and vmx.c. CVE-2015-7969 Multiple memory leaks in Xen 4.0 through 4.6.x allow local guest administrators or domains with certain permission to cause a denial of service (memory consumption) via a large number of 'teardowns' of domains with the vcpu pointer array allocated using the (1) XEN_DOMCTL_max_vcpus hypercall or the xenoprofile state vcpu pointer array allocated using the (2) XENOPROF_get_buffer or (3) XENOPROF_set_passive hypercall. CVE-2015-7970 The p2m_pod_emergency_sweep function in arch/x86/mm/p2m-pod.c in Xen 3.4.x, 3.5.x, and 3.6.x is not preemptible, which allows local x86 HVM guest administrators to cause a denial of service (CPU consumption and possibly reboot) via crafted memory contents that triggers a 'time-consuming linear scan,' related to Populate-on-Demand. CVE-2015-7971 Xen 3.2.x through 4.6.x does not limit the number of printk console messages when logging certain pmu and profiling hypercalls, which allows local guests to cause a denial of service via a sequence of crafted (1) HYPERCALL_xenoprof_op hypercalls, which are not properly handled in the do_xenoprof_op function in common/xenoprof.c, or (2) HYPERVISOR_xenpmu_op hypercalls, which are not properly handled in the do_xenpmu_op function in arch/x86/cpu/vpmu.c. CVE-2015-7972 The (1) libxl_set_memory_target function in tools/libxl/libxl.c and (2) libxl__build_post function in tools/libxl/libxl_dom.c in Xen 3.4.x through 4.6.x do not properly calculate the balloon size when using the populate-on-demand (PoD) system, which allows local HVM guest users to cause a denial of service (guest crash) via unspecified vectors related to 'heavy memory pressure.' CVE-2015-8104 The KVM subsystem in the Linux kernel through 4.2.6, and Xen 4.3.x through 4.6.x, allows guest OS users to cause a denial of service (host OS panic or hang) by triggering many #DB (aka Debug) exceptions, related to svm.c. CVE-2015-8339 The memory_exchange function in common/memory.c in Xen 3.2.x through 4.6.x does not properly hand back pages to a domain, which might allow guest OS administrators to cause a denial of service (host crash) via unspecified vectors related to domain teardown. CVE-2015-8340 The memory_exchange function in common/memory.c in Xen 3.2.x through 4.6.x does not properly release locks, which might allow guest OS administrators to cause a denial of service (deadlock or host crash) via unspecified vectors, related to XENMEM_exchange error handling. CVE-2015-8550 Xen, when used on a system providing PV backends, allows local guest OS administrators to cause a denial of service (host OS crash) or gain privileges by writing to memory shared between the frontend and backend, aka a double fetch vulnerability. CVE-2015-8554 Buffer overflow in hw/pt-msi.c in Xen 4.6.x and earlier, when using the qemu-xen-traditional (aka qemu-dm) device model, allows local x86 HVM guest administrators to gain privileges by leveraging a system with access to a passed-through MSI-X capable physical PCI device and MSI-X table entries, related to a 'write path.' CVE-2015-8555 Xen 4.6.x, 4.5.x, 4.4.x, 4.3.x, and earlier do not initialize x86 FPU stack and XMM registers when XSAVE/XRSTOR are not used to manage guest extended register state, which allows local guest domains to obtain sensitive information from other domains via unspecified vectors. CVE-2015-8615 The hvm_set_callback_via function in arch/x86/hvm/irq.c in Xen 4.6 does not limit the number of printk console messages when logging the new callback method, which allows local HVM guest OS users to cause a denial of service via a large number of changes to the callback method (HVM_PARAM_CALLBACK_IRQ). CVE-2016-1570 The PV superpage functionality in arch/x86/mm.c in Xen 3.4.0, 3.4.1, and 4.1.x through 4.6.x allows local PV guests to obtain sensitive information, cause a denial of service, gain privileges, or have unspecified other impact via a crafted page identifier (MFN) to the (1) MMUEXT_MARK_SUPER or (2) MMUEXT_UNMARK_SUPER sub-op in the HYPERVISOR_mmuext_op hypercall or (3) unknown vectors related to page table updates. CVE-2016-1571 The paging_invlpg function in include/asm-x86/paging.h in Xen 3.3.x through 4.6.x, when using shadow mode paging or nested virtualization is enabled, allows local HVM guest users to cause a denial of service (host crash) via a non-canonical guest address in an INVVPID instruction, which triggers a hypervisor bug check. CVE-2016-2270 Xen 4.6.x and earlier allows local guest administrators to cause a denial of service (host reboot) via vectors related to multiple mappings of MMIO pages with different cachability settings. CVE-2016-2271 VMX in Xen 4.6.x and earlier, when using an Intel or Cyrix CPU, allows local HVM guest users to cause a denial of service (guest crash) via vectors related to a non-canonical RIP.
