Xen 4.4.x, when running a 64-bit kernel on an ARM system, does not properly handle traps from the guest domain that use a different address width, which allows local guest users to cause a denial of service (host crash) via a crafted 32-bit process. | |||||
CVE-2014-3715 | 1 Xen | 1 Xen | 2018-10-30 | 3.3 LOW | N/A |
Buffer overflow in Xen 4.4.x allows local users to read system memory or cause a denial of service (crash) via a crafted 32-bit guest kernel, related to searching for an appended DTB. | |||||
CVE-2014-2915 | 1 Xen | 1 Xen | 2018-10-30 | 5.5 MEDIUM | N/A |
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. | |||||
CVE-2015-1563 | 2 Fedoraproject, Xen | 2 Fedora, Xen | 2018-10-30 | 2.1 LOW | N/A |
The ARM GIC distributor virtualization in Xen 4.4.x and 4.5.x allows local guests to cause a denial of service by causing a large number messages to be logged. | |||||
CVE-2015-7969 | 1 Xen | 1 Xen | 2018-10-30 | 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. | |||||
