CVE-2013-1918 1 Xen 1 Xen 2025-04-11 N/A
Certain page table manipulation operations in Xen 4.1.x, 4.2.x, and earlier are not preemptible, which allows local PV kernels to cause a denial of service via vectors related to "deep page table traversal."
CVE-2012-4536 1 Xen 1 Xen 2025-04-11 N/A
The (1) domain_pirq_to_emuirq and (2) physdev_unmap_pirq functions in Xen 2.2 allows local guest OS administrators to cause a denial of service (Xen crash) via a crafted pirq value that triggers an out-of-bounds read.
CVE-2012-4538 1 Xen 1 Xen 2025-04-11 N/A
The HVMOP_pagetable_dying hypercall in Xen 4.0, 4.1, and 4.2 does not properly check the pagetable state when running on shadow pagetables, which allows a local HVM guest OS to cause a denial of service (hypervisor crash) via unspecified vectors.
CVE-2012-4539 1 Xen 1 Xen 2025-04-11 N/A
Xen 4.0 through 4.2, when running 32-bit x86 PV guests on 64-bit hypervisors, allows local guest OS administrators to cause a denial of service (infinite loop and hang or crash) via invalid arguments to GNTTABOP_get_status_frames, aka "Grant table hypercall infinite loop DoS vulnerability."
CVE-2013-1917 1 Xen 1 Xen 2025-04-11 N/A
Xen 3.1 through 4.x, when running 64-bit hosts on Intel CPUs, does not clear the NT flag when using an IRET after a SYSENTER instruction, which allows PV guest users to cause a denial of service (hypervisor crash) by triggering a #GP fault, which is not properly handled by another IRET instruction.
CVE-2012-5511 1 Xen 1 Xen 2025-04-11 N/A
Stack-based buffer overflow in the dirty video RAM tracking functionality in Xen 3.4 through 4.1 allows local HVM guest OS administrators to cause a denial of service (crash) via a large bitmap image.
CVE-2012-4544 2 Redhat, Xen 2 Enterprise Linux, Xen 2025-04-11 N/A
The PV domain builder in Xen 4.2 and earlier does not validate the size of the kernel or ramdisk (1) before or (2) after decompression, which allows local guest administrators to cause a denial of service (domain 0 memory consumption) via a crafted (a) kernel or (b) ramdisk.
CVE-2012-4411 1 Xen 1 Xen 2025-04-11 N/A
The graphical console in Xen 4.0, 4.1 and 4.2 allows local OS guest administrators to obtain sensitive host resource information via the qemu monitor. NOTE: this might be a duplicate of CVE-2007-0998.
CVE-2013-6375 2 Opensuse, Xen 2 Opensuse, Xen 2025-04-11 N/A
Xen 4.2.x and 4.3.x, when using Intel VT-d for PCI passthrough, does not properly flush the TLB after clearing a present translation table entry, which allows local guest administrators to cause a denial of service or gain privileges via unspecified vectors related to an "inverted boolean parameter."
CVE-2013-4369 1 Xen 1 Xen 2025-04-11 N/A
The xlu_vif_parse_rate function in the libxlu library in Xen 4.2.x and 4.3.x allows local users to cause a denial of service (NULL pointer dereference) by using the "@" character as the VIF rate configuration.
CVE-2013-4416 1 Xen 1 Xen 2025-04-11 N/A
The Ocaml xenstored implementation (oxenstored) in Xen 4.1.x, 4.2.x, and 4.3.x allows local guest domains to cause a denial of service (domain shutdown) via a large message reply.
CVE-2013-4329 1 Xen 1 Xen 2025-04-11 N/A
The xenlight library (libxl) in Xen 4.0.x through 4.2.x, when IOMMU is disabled, provides access to a busmastering-capable PCI passthrough device before the IOMMU setup is complete, which allows local HVM guest domains to gain privileges or cause a denial of service via a DMA instruction.
CVE-2011-3131 2 Redhat, Xen 2 Enterprise Linux, Xen 2025-04-11 N/A
Xen 4.1.1 and earlier allows local guest OS kernels with control of a PCI[E] device to cause a denial of service (CPU consumption and host hang) via many crafted DMA requests that are denied by the IOMMU, which triggers a livelock.
CVE-2013-4375 2 Qemu, Xen 2 Qemu, Xen 2025-04-11 N/A
The qdisk PV disk backend in qemu-xen in Xen 4.2.x and 4.3.x before 4.3.1, and qemu 1.1 and other versions, allows local HVM guests to cause a denial of service (domain grant reference consumption) via unspecified vectors.
CVE-2009-1758 3 Linux, Redhat, Xen 3 Linux Kernel, Enterprise Linux, Xen 2025-04-09 N/A
The hypervisor_callback function in Xen, possibly before 3.4.0, as applied to the Linux kernel 2.6.30-rc4, 2.6.18, and probably other versions allows guest user applications to cause a denial of service (kernel oops) of the guest OS by triggering a segmentation fault in "certain address ranges."
CVE-2009-3525 2 Redhat, Xen 2 Enterprise Linux, Xen 2025-04-09 N/A
The pyGrub boot loader in Xen 3.0.3, 3.3.0, and Xen-3.3.1 does not support the password option in grub.conf for para-virtualized guests, which allows attackers with access to the para-virtualized guest console to boot the guest or modify the guest's kernel boot parameters without providing the expected password.
CVE-2007-6416 2 Redhat, Xen 2 Enterprise Linux, Xen 2025-04-09 N/A
The copy_to_user function in the PAL emulation functionality for Xen 3.1.2 and earlier, when running on ia64 systems, allows HVM guest users to access arbitrary physical memory by triggering certain mapping operations.
CVE-2007-1320 6 Debian, Fedoraproject, Opensuse and 3 more 7 Debian Linux, Fedora, Fedora Core and 4 more 2025-04-09 N/A
Multiple heap-based buffer overflows in the cirrus_invalidate_region function in the Cirrus VGA extension in QEMU 0.8.2, as used in Xen and possibly other products, might allow local users to execute arbitrary code via unspecified vectors related to "attempting to mark non-existent regions as dirty," aka the "bitblt" heap overflow.
CVE-2007-0998 2 Redhat, Xen 3 Enterprise Linux, Fedora Core, Qemu 2025-04-09 N/A
The VNC server implementation in QEMU, as used by Xen and possibly other environments, allows local users of a guest operating system to read arbitrary files on the host operating system via unspecified vectors related to QEMU monitor mode, as demonstrated by mapping files to a CDROM device. NOTE: some of these details are obtained from third party information.
CVE-2008-3687 1 Xen 2 Xen, Xen Flask Module 2025-04-09 N/A
Heap-based buffer overflow in the flask_security_label function in Xen 3.3, when compiled with the XSM:FLASK module, allows unprivileged domain users (domU) to execute arbitrary code via the flask_op hypercall.
