CVE-2014-5146

CVE-2014-5146 affects Xen 4.2.x–4.4.x before the xsa97-hap patch. When using Hardware Assisted Paging (HAP), certain MMU virtualization ops are not preemptible, allowing a local HVM guest to trigger a DoS by consuming all vCPUs for pages assigned to the guest. It is described as a separate issue ...

CVE-2014-5149

CVE-2014-5149 affects Xen 4.2.x–4.4.x when using shadow pagetables. Certain MMU virtualization operations are not preemptible, allowing a local HVM guest to trigger a denial of service by processing every page assigned to the guest (vcpu consumption). This is described as a different vulnerabilit...

CVE-2013-1442

CVE-2013-1442 affects Xen 4.0–4.3.x on CPUs with AVX or LWP. The issue is that XSAVE/XRSTOR state extension of a saved/restored vCPU may leave residual data in registers after touching other extended registers, enabling a local guest OS to read sensitive information from those registers. The vuln...
