CVE-2017-10920 at MITRE

Description

The grant-table feature in Xen through 4.8.x mishandles a GNTMAP_device_map and GNTMAP_host_map mapping, when followed by only a GNTMAP_host_map unmapping, which allows guest OS users to cause a denial of service (count mismanagement and memory corruption) or obtain privileged host OS access, aka XSA-224 bug 1.

Note from the SUSE Security Team on the xen package

This issue likely only affects the XEN hypervisor itself, unless otherwise stated. The userland utilities in -tools and libraries in -libs are shipped together with the xen hypervisor as they are built from one source and do not contain hypervisor specific fixes.
