CWE-200  (opens in a new tab)

How to fix?

Upgrade Ubuntu:14.04 xen to version 4.4.0-0ubuntu5.1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream xen package and not the xen package as distributed by Ubuntu. See How to fix? for Ubuntu:14.04 relevant fixed versions and status.

The alloc_domain_struct function in arch/arm/domain.c in Xen 4.4.x, when running on an ARM platform, does not properly initialize the structure containing the grant table pages for a domain, which allows local guest administrators to obtain sensitive information via the GNTTABOP_setup_table subhypercall.
