These security issues were fixed:
- CVE-2016-7092: The get_page_from_l3e function in arch/x86/mm.c in Xen
 allowed local 32-bit PV guest OS administrators to gain host OS
 privileges via vectors related to L3 recursive pagetables (bsc#995785)
- CVE-2016-7093: Xen allowed local HVM guest OS administrators to
 overwrite hypervisor memory and consequently gain host OS privileges by
 leveraging mishandling of instruction pointer truncation during
 emulation (bsc#995789)
- CVE-2016-7094: Buffer overflow in Xen allowed local x86 HVM guest OS
 administrators on guests running with shadow paging to cause a denial of
 service via a pagetable update (bsc#995792)
- CVE-2016-7154: Use-after-free vulnerability in the FIFO event channel
 code in Xen allowed local guest OS administrators to cause a denial of
 service (host crash) and possibly execute arbitrary code or obtain
 sensitive information via an invalid guest frame number (bsc#997731)
- CVE-2016-6836: VMWARE VMXNET3 NIC device allowed privileged user inside
 the guest to leak information. It occurred while processing transmit(tx)
 queue, when it reaches the end of packet (bsc#994761)
- CVE-2016-6888: A integer overflow int the VMWARE VMXNET3 NIC device
 support, during the initialisation of new packets in the device, could
 have allowed a privileged user inside guest to crash the Qemu instance
 resulting in DoS (bsc#994772)
- CVE-2016-6833: A use-after-free issue in the VMWARE VMXNET3 NIC device
 support allowed privileged user inside guest to crash the Qemu instance
 resulting in DoS (bsc#994775)
- CVE-2016-6835: Buffer overflow in the VMWARE VMXNET3 NIC device support,
 causing an OOB read access (bsc#994625)
- CVE-2016-6834: A infinite loop during packet fragmentation in the VMWARE
 VMXNET3 NIC device support allowed privileged user inside guest to crash
 the Qemu instance resulting in DoS (bsc#994421)
- CVE-2016-6258: The PV pagetable code in arch/x86/mm.c in Xen allowed
 local 32-bit PV guest OS administrators to gain host OS privileges by
 leveraging fast-paths for updating pagetable entries (bsc#988675)
These non-security issues were fixed:
- bsc#993507: virsh detach-disk failing to detach disk
- bsc#991934: Xen hypervisor crash in csched_acct
- bsc#992224: During boot of Xen Hypervisor, Failed to get contiguous
 memory for DMA
- bsc#970135: New virtualization project clock test randomly fails on Xen
- bsc#994136: Unplug also SCSI disks in qemu-xen-traditional for upstream
 unplug protocol
- bsc#994136: xen_platform: unplug also SCSI disks in qemu-xen
- bsc#971949: xl: Support (by ignoring) xl migrate --live. xl migrations
 are always live
- bsc#990970: Add PMU support for Intel E7-8867 v4 (fam=6, model=79)
- bsc#966467: Live Migration SLES 11 SP3 to SP4 on AMD");
