CVE-2012-5525 1 Xen 1 Xen 2025-04-11 N/A
The get_page_from_gfn hypercall function in Xen 4.2 allows local PV guest OS administrators to cause a denial of service (crash) via a crafted GFN that triggers a buffer over-read.
CVE-2012-6033 1 Xen 1 Xen 2025-04-11 N/A
The do_tmem_control function in the Transcendent Memory (TMEM) in Xen 4.0, 4.1, and 4.2 does not properly check privileges, which allows local guest OS users to access control stack operations via unspecified vectors. NOTE: this issue was originally published as part of CVE-2012-3497, which was too general; CVE-2012-3497 has been SPLIT into this ID and others.
CVE-2012-6035 1 Xen 1 Xen 2025-04-11 N/A
The do_tmem_destroy_pool function in the Transcendent Memory (TMEM) in Xen 4.0, 4.1, and 4.2 does not properly validate pool ids, which allows local guest OS users to cause a denial of service (memory corruption and host crash) or execute arbitrary code via unspecified vectors. NOTE: this issue was originally published as part of CVE-2012-3497, which was too general; CVE-2012-3497 has been SPLIT into this ID and others.
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-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-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-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-2013-2072 2 Debian, Xen 2 Debian Linux, Xen 2025-04-11 N/A
Buffer overflow in the Python bindings for the xc_vcpu_setaffinity call in Xen 4.0.x, 4.1.x, and 4.2.x allows local administrators with permissions to configure VCPU affinity to cause a denial of service (memory corruption and xend toolstack crash) and possibly gain privileges via a crafted cpumap.
CVE-2012-3433 1 Xen 1 Xen 2025-04-11 N/A
Xen 4.0 and 4.1 allows local HVM guest OS kernels to cause a denial of service (domain 0 VCPU hang and kernel panic) by modifying the physical address space in a way that triggers excessive shared page search time during the p2m teardown.
CVE-2012-3498 2 Citrix, Xen 2 Xenserver, Xen 2025-04-11 N/A
PHYSDEVOP_map_pirq in Xen 4.1 and 4.2 and Citrix XenServer 6.0.2 and earlier allows local HVM guest OS kernels to cause a denial of service (host crash) and possibly read hypervisor or guest memory via vectors related to a missing range check of map->index.
CVE-2012-6333 1 Xen 1 Xen 2025-04-11 N/A
Multiple HVM control operations in Xen 3.4 through 4.2 allow local HVM guest OS administrators to cause a denial of service (physical CPU consumption) via a large input.
CVE-2012-2934 2 Redhat, Xen 2 Enterprise Linux, Xen 2025-04-11 N/A
Xen 4.0, and 4.1, when running a 64-bit PV guest on "older" AMD CPUs, does not properly protect against a certain AMD processor bug, which allows local guest OS users to cause a denial of service (host hang) via sequential execution of instructions across a non-canonical boundary, a different vulnerability than CVE-2012-0217.
CVE-2013-6400 1 Xen 1 Xen 2025-04-11 N/A
Xen 4.2.x and 4.3.x, when using Intel VT-d and a PCI device has been assigned, does not clear the flag that suppresses IOMMU TLB flushes when unspecified errors occur, which causes the TLB entries to not be flushed and allows local guest administrators to cause a denial of service (host crash) or gain privileges via unspecified vectors.
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-2013-4361 1 Xen 1 Xen 2025-04-11 N/A
The fbld instruction emulation in Xen 3.3.x through 4.3.x does not use the correct variable for the source effective address, which allows local HVM guests to obtain hypervisor stack information by reading the values used by the instruction.
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-2014-1642 1 Xen 1 Xen 2025-04-11 N/A
The IRQ setup in Xen 4.2.x and 4.3.x, when using device passthrough and configured to support a large number of CPUs, frees certain memory that may still be intended for use, which allows local guest administrators to cause a denial of service (memory corruption and hypervisor crash) and possibly execute arbitrary code via vectors related to an out-of-memory error that triggers a (1) use-after-free or (2) double free.
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.
