CVE-2015-7969 1 Xen 1 Xen 2024-11-21 4.9 MEDIUM N/A
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-2015-7835 1 Xen 1 Xen 2024-11-21 7.2 HIGH N/A
The mod_l2_entry function in arch/x86/mm.c in Xen 3.4 through 4.6.x does not properly validate level 2 page table entries, which allows local PV guest administrators to gain privileges via a crafted superpage mapping.
CVE-2015-7814 1 Xen 1 Xen 2024-11-21 4.7 MEDIUM N/A
Race condition in the relinquish_memory function in arch/arm/domain.c in Xen 4.6.x and earlier allows local domains with partial management control to cause a denial of service (host crash) via vectors involving the destruction of a domain and using XENMEM_decrease_reservation to reduce the memory of the domain.
CVE-2015-7813 1 Xen 1 Xen 2024-11-21 2.1 LOW N/A
Xen 4.4.x, 4.5.x, and 4.6.x does not limit the number of printk console messages when reporting unimplemented hypercalls, which allows local guests to cause a denial of service via a sequence of (1) HYPERVISOR_physdev_op hypercalls, which are not properly handled in the do_physdev_op function in arch/arm/physdev.c, or (2) HYPERVISOR_hvm_op hypercalls, which are not properly handled in the do_hvm_op function in arch/arm/hvm.c.
CVE-2015-7812 1 Xen 1 Xen 2024-11-21 4.9 MEDIUM N/A
The hypercall_create_continuation function in arch/arm/domain.c in Xen 4.4.x through 4.6.x allows local guest users to cause a denial of service (host crash) via a preemptible hypercall to the multicall interface.
CVE-2015-7504 3 Debian, Qemu, Xen 3 Debian Linux, Qemu, Xen 2024-11-21 4.6 MEDIUM 8.8 HIGH
Heap-based buffer overflow in the pcnet_receive function in hw/net/pcnet.c in QEMU allows guest OS administrators to cause a denial of service (instance crash) or possibly execute arbitrary code via a series of packets in loopback mode.
CVE-2015-7311 1 Xen 1 Xen 2024-11-21 3.6 LOW N/A
libxl in Xen 4.1.x through 4.6.x does not properly handle the readonly flag on disks when using the qemu-xen device model, which allows local guest users to write to a read-only disk image.
CVE-2015-6815 7 Arista, Canonical, Fedoraproject and 4 more 11 Eos, Ubuntu Linux, Fedora and 8 more 2024-11-21 2.7 LOW 3.5 LOW
The process_tx_desc function in hw/net/e1000.c in QEMU before 2.4.0.1 does not properly process transmit descriptor data when sending a network packet, which allows attackers to cause a denial of service (infinite loop and guest crash) via unspecified vectors.
CVE-2015-6654 1 Xen 1 Xen 2024-11-21 2.1 LOW N/A
The xenmem_add_to_physmap_one function in arch/arm/mm.c in Xen 4.5.x, 4.4.x, and earlier does not limit the number of printk console messages when reporting a failure to retrieve a reference on a foreign page, which allows remote domains to cause a denial of service by leveraging permissions to map the memory of a foreign guest.
CVE-2015-5307 5 Canonical, Debian, Linux and 2 more 5 Ubuntu Linux, Debian Linux, Linux Kernel and 2 more 2024-11-21 4.9 MEDIUM N/A
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-2015-5166 2 Fedoraproject, Xen 2 Fedora, Xen 2024-11-21 7.2 HIGH N/A
Use-after-free vulnerability in QEMU in Xen 4.5.x and earlier does not completely unplug emulated block devices, which allows local HVM guest users to gain privileges by unplugging a block device twice.
CVE-2015-5165 7 Arista, Debian, Fedoraproject and 4 more 24 Eos, Debian Linux, Fedora and 21 more 2024-11-21 9.3 HIGH N/A
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-2015-5154 4 Fedoraproject, Qemu, Suse and 1 more 8 Fedora, Qemu, Linux Enterprise Debuginfo and 5 more 2024-11-21 7.2 HIGH N/A
Heap-based buffer overflow in the IDE subsystem in QEMU, as used in Xen 4.5.x and earlier, when the container has a CDROM drive enabled, allows local guest users to execute arbitrary code on the host via unspecified ATAPI commands.
CVE-2015-4164 1 Xen 1 Xen 2024-11-21 4.9 MEDIUM N/A
The compat_iret function in Xen 3.1 through 4.5 iterates the wrong way through a loop, which allows local 32-bit PV guest administrators to cause a denial of service (large loop and system hang) via a hypercall_iret call with EFLAGS.VM set.
CVE-2015-4163 1 Xen 1 Xen 2024-11-21 4.9 MEDIUM N/A
GNTTABOP_swap_grant_ref in Xen 4.2 through 4.5 does not check the grant table operation version, which allows local guest domains to cause a denial of service (NULL pointer dereference) via a hypercall without a GNTTABOP_setup_table or GNTTABOP_set_version.
CVE-2015-4105 1 Xen 1 Xen 2024-11-21 4.9 MEDIUM N/A
Xen 3.3.x through 4.5.x enables logging for PCI MSI-X pass-through error messages, which allows local x86 HVM guests to cause a denial of service (host disk consumption) via certain invalid operations.
CVE-2015-4104 1 Xen 1 Xen 2024-11-21 7.8 HIGH N/A
Xen 3.3.x through 4.5.x does not properly restrict access to PCI MSI mask bits, which allows local x86 HVM guest users to cause a denial of service (unexpected interrupt and host crash) via unspecified vectors.
CVE-2015-4103 1 Xen 1 Xen 2024-11-21 4.9 MEDIUM N/A
Xen 3.3.x through 4.5.x does not properly restrict write access to the host MSI message data field, which allows local x86 HVM guest administrators to cause a denial of service (host interrupt handling confusion) via vectors related to qemu and accessing spanning multiple fields.
CVE-2015-3456 3 Qemu, Redhat, Xen 5 Qemu, Enterprise Linux, Enterprise Virtualization and 2 more 2024-11-21 7.7 HIGH N/A
The Floppy Disk Controller (FDC) in QEMU, as used in Xen 4.5.x and earlier and KVM, allows local guest users to cause a denial of service (out-of-bounds write and guest crash) or possibly execute arbitrary code via the (1) FD_CMD_READ_ID, (2) FD_CMD_DRIVE_SPECIFICATION_COMMAND, or other unspecified commands, aka VENOM.
