| DATE | CVE | VULNERABILITY TITLE | RISK |
|---|---|---|---|
| 2014-06-05 | CVE-2014-3967 | Denial of Service vulnerability in Xen 'HVM MSI injection' The HVMOP_inject_msi function in Xen 4.2.x, 4.3.x, and 4.4.x does not properly check the return value from the IRQ setup check, which allows local HVM guest administrators to cause a denial of service (NULL pointer dereference and crash) via unspecified vectors. | 5.5 |
| 2014-05-07 | CVE-2014-3124 | Permissions, Privileges, and Access Controls vulnerability in XEN The HVMOP_set_mem_type control in Xen 4.1 through 4.4.x allows local guest HVM administrators to cause a denial of service (hypervisor crash) or possibly execute arbitrary code by leveraging a separate qemu-dm vulnerability to trigger invalid page table translations for unspecified memory page types. | 6.7 |
| 2014-05-02 | CVE-2014-3125 | Permissions, Privileges, and Access Controls vulnerability in XEN 4.4.0 Xen 4.4.x, when running on an ARM system, does not properly context switch the CNTKCTL_EL1 register, which allows local guest users to modify the hardware timers and cause a denial of service (crash) via unspecified vectors. | 6.2 |
| 2014-04-28 | CVE-2014-2986 | Improper Input Validation vulnerability in XEN 4.4.0 The vgic_distr_mmio_write function in the virtual guest interrupt controller (GIC) distributor (arch/arm/vgic.c) in Xen 4.4.x, when running on an ARM system, allows local guest users to cause a denial of service (NULL pointer dereference and host crash) via unspecified vectors. | 5.5 |
| 2014-04-24 | CVE-2014-2915 | Permissions, Privileges, and Access Controls vulnerability in XEN 4.4.0 Xen 4.4.x, when running on ARM systems, does not properly restrict access to hardware features, which allows local guest users to cause a denial of service (host or guest crash) via unspecified vectors, related to (1) cache control, (2) coprocessors, (3) debug registers, and (4) other unspecified registers. | 5.5 |
| 2014-04-15 | CVE-2014-2580 | Resource Management Errors vulnerability in XEN The netback driver in Xen, when using certain Linux versions that do not allow sleeping in softirq context, allows local guest administrators to cause a denial of service ("scheduling while atomic" error and host crash) via a malformed packet, which causes a mutex to be taken when trying to disable the interface. | 4.4 |
| 2014-04-01 | CVE-2014-1896 | Improper Input Validation vulnerability in XEN The (1) do_send and (2) do_recv functions in io.c in libvchan in Xen 4.2.x, 4.3.x, and 4.4-RC series allows local guests to cause a denial of service or possibly gain privileges via crafted xenstore ring indexes, which triggers a "read or write past the end of the ring." | 4.9 |
| 2014-04-01 | CVE-2014-1895 | Numeric Errors vulnerability in XEN Off-by-one error in the flask_security_avc_cachestats function in xsm/flask/flask_op.c in Xen 4.2.x and 4.3.x, when the maximum number of physical CPUs are in use, allows local users to cause a denial of service (host crash) or obtain sensitive information from hypervisor memory by leveraging a FLASK_AVC_CACHESTAT hypercall, which triggers a buffer over-read. | 5.8 |
| 2014-04-01 | CVE-2014-1894 | Numeric Errors vulnerability in XEN Multiple integer overflows in unspecified suboperations in the flask hypercall in Xen 3.2.x and earlier, when XSM is enabled, allow local users to cause a denial of service (processor fault) via unspecified vectors, a different vulnerability than CVE-2014-1891, CVE-2014-1892, and CVE-2014-1893. | 5.2 |
| 2014-04-01 | CVE-2014-1893 | Numeric Errors vulnerability in XEN Multiple integer overflows in the (1) FLASK_GETBOOL and (2) FLASK_SETBOOL suboperations in the flask hypercall in Xen 4.1.x, 3.3.x, 3.2.x, and earlier, when XSM is enabled, allow local users to cause a denial of service (processor fault) via unspecified vectors, a different vulnerability than CVE-2014-1891, CVE-2014-1892, and CVE-2014-1894. | 5.2 |
