XSA-108 patch from Xen community

The Xen community has released details on XSA-108 / CVE-2014-7188 here:

  http://xenbits.xen.org/xsa/advisory-108.html
  https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2014-7188

It affects Xen 4.1+, so that's Fedora 19 through rawhide if I remember correctly.  The patch is available here:

  http://xenbits.xen.org/xsa/xsa108.patch

The bug allows an HVM guest (including PVHVM) to read ~ 3KB worth of memory from the hypervisor or other guests.
