These security issues were fixed:
- 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-2016-7092: 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-2016-5403: Unbounded memory allocation allowed a guest administrator
 to cause a denial of service of the host (bsc#990923)
- CVE-2016-6351: The esp_do_dma function in hw/scsi/esp.c, when built with
 ESP/NCR53C9x controller emulation support, allowed local guest OS
 administrators to cause a denial of service (out-of-bounds write and
 QEMU process crash) or execute arbitrary code on the host via vectors
 involving DMA read into ESP command buffer (bsc#990843)
- 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)
- CVE-2016-5338: The (1) esp_reg_read and (2) esp_reg_write functions
 allowed local guest OS administrators to cause a denial of service (QEMU
 process crash) or execute arbitrary code on the host via vectors related
 to the information transfer buffer (bsc#983984)
- CVE-2016-5238: The get_cmd function in hw/scsi/esp.c might have allowed
 local guest OS administrators to cause a denial of service
 (out-of-bounds write and QEMU process crash) via vectors related to
 reading from the information transfer buffer in non-DMA mode (bsc#982960)
- CVE-2016-4453: The vmsvga_fifo_run function allowed local guest OS
 administrators to cause a denial of service (infinite loop and QEMU
 process crash) via a VGA command (bsc#982225)
- CVE-2016-4454: The vmsvga_fifo_read_raw function allowed local guest OS
 administrators to obtain sensitive host memory information or cause a
 denial of service (QEMU process crash) by changing FIFO registers and
 issuing a VGA command, which triggered an out-of-bounds read (bsc#982224)
- CVE-2014-3672: The qemu implementation in libvirt Xen allowed local
 guest OS users to cause a denial of service (host disk consumption) by
 writing to stdout or stderr (bsc#981264)
- CVE-2016-4441: The get_cmd function in the 53C9X Fast SCSI Controller
 (FSC) support did not properly check DMA length, which allowed local
 guest OS administrators to cause a denial of service (out-of-bounds
 write and QEMU process crash) via unspecified vectors, involving an SCSI
 command (bsc#980724)
- CVE-2016-4439: The esp_reg_write function in the 53C9X Fast SCSI
 Controller (FSC) support did not properly check command buffer length,
 which allowed local guest OS administrators to cause a denial of service
 (out-of-bounds write and QEMU process ... [Please see the references for more information on the vulnerabilities]");
