| DATE | CVE | VULNERABILITY TITLE | RISK |
|---|---|---|---|
| 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 |
| 2014-04-01 | 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 |
| 2014-03-28 | CVE-2014-2599 | Improper Input Validation vulnerability in XEN The HVMOP_set_mem_access HVM control operations in Xen 4.1.x for 32-bit and 4.1.x through 4.4.x for 64-bit allow local guest administrators to cause a denial of service (CPU consumption) by leveraging access to certain service domains for HVM guests and a large input. | 4.9 |
