  <description>
XEN was updated to fix two security issues and bugs.

Security issues fixed:
* CVE-2015-3340: 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-2015-2751: Xen, when using toolstack disaggregation, allowed remote
  domains with partial management control to cause a denial of service
  (host lock) via unspecified domctl operations.

* CVE-2015-2752: The XEN_DOMCTL_memory_mapping hypercall in Xen, when
  using a PCI passthrough device, was not preemptable, which allowed local
  x86 HVM domain users to cause a denial of service (host CPU consumption)
  via a crafted request to the device model (qemu-dm).

* CVE-2015-3456: 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.

Bugs fixed:
- xentop: Fix memory leak on read failure
