   An update that fixes two vulnerabilities is now available.

Description:


   The XEN hypervisor was updated to fix two security issues:

   - Fixed a buffer overflow in the floppy drive emulation, which could be
     used to denial of service attacks or potential code execution against
     the host. (CVE-2015-3456)
   - Xen did not initialize certain fields, which allowed certain remote
     service domains to obtain sensitive information from memory via a (1)
     XEN_DOMCTL_gettscinfo or (2) XEN_SYSCTL_getdomaininfolist request.
     (CVE-2015-3340)
