1) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2013-2077)
CWE-ID: CWE-264 - Permissions, Privileges, and Access Controls

The vulnerability allows a remote #AU# to perform a denial of service (DoS) attack.
Xen 4.0.x, 4.1.x, and 4.2.x does not properly restrict the contents of a XRSTOR, which allows local PV guest users to cause a denial of service (unhandled exception and hypervisor crash) via unspecified vectors.
